Wind pumps for irrigating greenhouse crops: Comparison in different socio-economical frameworks  

Science Journals Connector (OSTI)

A simple methodology was used to compare the economic feasibility of wind pump technology, solar photovoltaic pumping, diesel generators, and connection to the electrical grid to provide energy for pumping irrigation water in commercial greenhouses in Spain, Cuba and Pakistan (countries with different developmental backgrounds). The analysis took into account wind resources, distance to the grid, water storage tank volume requirements, and planting dates. Comparisons were made in terms of the levelised cost of energy associated with each system. For all three countries, if a grid connection was already in place, installing wind pumps would be economically unwise. Where no grid connection exists, the distance to the grid and the wind resource available are key factors to be taken into consideration when deciding between options: a 10% increase in the average wind speed is equivalent to a 20% reduction in the distance to the grid in terms of costs return. Finally, the water elevation has a major influence on the economic feasibility of wind pump technology, much more than, for example, on solar photovoltaic pumping technology. The results reveal that, generally, the critical factors to consider when making energy management decisions differ depending between countries. In Spain, the proximity of the electrical grid makes the connection to it the best option. In Pakistan, scarce wind resources are a serious limiting factor. Cuba, however, has good wind resources; water elevation, distance to the grid and water storage needed are the critical factors when determining the economic feasibility of wind pumping there.

Stirling engines and irrigation pumping  

SciTech Connect (OSTI)

This report was prepared in support of the Renewable Energy Applications and Training Project sponsored by the US Agency for International Development for which ORNL provides technical assistance. It briefly outlines the performance that might be achievable from various kinds of Stirling-engine-driven irrigation pumps. Some emphasis is placed on the very simple liquid-piston engines that have been the subject of research in recent years and are suitable for manufacture in less well-developed countries. In addition to the results quoted here (possible limits on M/sup 4/ and pumping head for different-size engines and various operating conditions), the method of calculation is described in sufficient detail for engineers to apply the techniques to other Stirling engine designs for comparison. The liquid-piston Fluidyne is a form of Stirling engine sharing many of the characteristics of conventional kinematic and free-piston Stirling machines. The use of liquid pistons, however, gives it some unique advantages as well as certain problems that are not encountered or are not important in engines with solid pistons. Because the output is naturally available in the form of an oscillating liquid flow or a fluctuating pressure, the Fluidyne is well suited to liquid pumping, but other applications have also been considered. 27 refs., 7 figs., 2 tabs.

Use of soil and vegetation spectroradiometry to investigate crop water use efficiency of a drip irrigated tomato  

Science Journals Connector (OSTI)

Abstract An agronomic research was conducted in Tuscany (Central Italy) to evaluate the effects of an advanced irrigation system on the water use efficiency (WUE) of a tomato crop and to investigate the ability of soil and vegetation spectroradiometry to detect and map WUE. Irrigation was applied following an innovative approach based on CropSense system. Soil water content was monitored at four soil depths (10, 20, 30 and 50cm) by a probe. Rainfall during the crop cycle reached 162mm and irrigation water applied with a drip system amounted to 207mm, distributed with 16 irrigation events. Tomato yield varied from 7.10 to 14.4kgm?2, with a WUE ranging from 19.1 to 38.9kgm?3. The irrigation system allowed a high yield levels and a low depth of water applied, as compared to seasonal ET crop estimated with Hargraves formula and with the literature data on irrigated tomato. Measurements were carried out on geo-referenced points to gather information on crop (crop yield, eighteen Vegetation indices, leaf area index) and on soil (spectroradiometric and traditional analysis). Eight VIs, out of nineteen ones analyzed, showed a significant relationship with georeferenced yield data; PVI maps seemed able to return the best response, before harvesting, to improve the knowledge of the area of cultivation and irrigation system. CropSense irrigation system reduced seasonal irrigation volumes. Some vegetation indexes were significantly correlated to tomato yield and well identify, a posteriori, crop area with low WUE; spectroradiometry can be a valuable tool to improve irrigated tomato field management.

Performance of late sown wheat crop under different planting geometries and irrigation regimes in arid climate  

Science Journals Connector (OSTI)

Proper orientation of plants in the field and management of soil moisture for appropriate utilization of land, water and environmental resources plays a significant role in the optimum development and functioning of vital plant organs. A two factor field experiment was conducted for two consecutive crop growth seasons viz. 200607 and 200708 at Research and Demonstration Farm, Regional Agricultural Economic Development Centre (RAEDC), Vehari, Pakistan to make a comparison of four different planting geometries viz. planting in 22cm apart rows under conventional, minimum and zero tillage, respectively and planting in 11cm apart rows under conventional tillage system. Wheat cultivar, Inqlab-91 was planted late in December. Crop was subjected to five irrigation levels in which irrigation was applied equivalent to 120%, 100%, 80%, 60% or 40% of ETo. Lower soil bulk density and penetration resistances at 1020cm soil depth were recorded with conventional tillage with either narrow or wider row spacing as compared to other planting geometries. The maximum values for LAI, LAD, TDM, productive tillers (m?2), 1000-grain weight and grain yield were recorded with planting geometry having 11cm apart rows under conventional tillage system along with irrigation level of 120% \\{ETo\\} that remained statistically at par with the same planting geometry subjected to the irrigation regime of 100% ETo. This planting geometry also resulted in minimum weed fresh biomass. It is concluded that late planted wheat crop planted in 11cm wide rows under conventional tillage irrigated @ 100% \\{ETo\\} may serve as an appropriate technology for enhancing the wheat productivity of late sown wheat crop under limited water supplies.

Effects of different irrigation regimes on yield and water use efficiency of cucumber crop  

Science Journals Connector (OSTI)

Abstract This study was conducted to investigate the effects of four irrigation regimes on yield, growth parameters and water use efficiency of cucumber crop under greenhouse cultivation. A field experiment was carried out at the experimental farm of Palestine Technical University Kadoorie, located at Tulkarm, Palestine. Cucumber seedlings were planted on 14 February 2012 in greenhouse at a rate of 1500 seedlings per 1000 square meters. Four irrigation regimes were examined during the growing period as follows: farmer irrigation (FI), tensiometer based irrigation (TI), irrigation at full \\{ETc\\} data (ETc), and irrigation at 70% of \\{ETc\\} (70% ETc). Plant data were collected during the growing period for evaluating the total yield, plant height, number of harvested fruits per plant, weight of harvested fruits per plant, dry matter of above and under ground parts. The results indicated that the 70% \\{ETc\\} treatment obtained the highest crop yield followed by ETc, FI, and TI treatments, respectively. On average, cucumber yield under 70% \\{ETc\\} treatment was 24%, 6% and 4% higher than that under TI, FI and \\{ETc\\} treatments, respectively. At the end of harvesting stage plant height, above-ground dry matter obtained by 70% \\{ETc\\} treatment was higher than the other treatments. The smallest plant height and dry matter was obtained under TI treatment. Results also indicated that, when using scheduled irrigation methods large amount of water were saved and found to be 139, 104 and 26mm for TI, 70% \\{ETc\\} and \\{ETc\\} treatments, respectively, compared to FI treatment. The highest water use efficiency (WUE) was obtained under 70% \\{ETc\\} treatment followed by ETc, TI and FI treatments, respectively.

Winter wheat with subsurface drip irrigation (SDI): Crop coefficients, water-use estimates, and effects of SDI on grain yield and water use efficiency  

Science Journals Connector (OSTI)

Abstract Winter wheat (Triticum aestivum L.) production in the North China Plain (NCP) is threatened by insufficient water supply. Interest in microirrigation is increasing in the NCP, while data and guidance for microirrigation scheduling are lacking. An accurate estimation of actual crop evapotranspiration (ETa) is critical for appropriate water management. In this study, therefore, the \\{SIMDualKc\\} model was calibrated with the data from a three-season experiment, and \\{ETa\\} of winter wheat with subsurface drip irrigation (SDI) was estimated with the dual crop coefficient approach and stress adjustments described in the FAO-56 using the data of the other two treatments. The mean value of basal crop coefficient (Kcb) for the winter wheat at the initial-, mid-, and late-season growth stages over the three seasons was 0.25, 1.06, and 0.34, respectively. Over the three growing seasons, the \\{ETa\\} for subsurface drip-irrigated wheat with three irrigation treatments ranged from 393 to 449mm. The Kc-local (ETa/ETo) values for the winter wheat with SDI were 0.340.80, 0.911.11, and 0.410.98, respectively, at the initial-, mid-, and late-season growth stages. Results indicated that the procedure of the dual Kc approach and stress adjustments simulated \\{ETa\\} of the winter wheat reasonably well, with the average absolute error (AAE) of 0.36mmd?1, the root mean square error (RMSE) of 0.43mmd?1,the index of agreement (d) of 0.98, the NashSutcliffe efficiency (NSE) of 0.91, and the RMSE-observations standard deviation ratio (RSR) of 0.31. Discrepancy between the simulated and measured data was mainly attributed to the assumption of a uniform distribution of soil water around an emitter. Irrigation rates have significant effects on ETa, grain yield and WUE. Based on effects of irrigation rates on grain yield and WUE, irrigation schedule for optimum yield and WUE was developed for winter wheat. It was estimated that grain yield and WUE of winter wheat with the optimum irrigation schedule was 7780kgha?1 and 1.83kgm?3, respectively. The simulated results can be used as a reference for irrigation schedule and water management for winter wheat in the NCP.

Wind energy for low head irrigation. Report for Oct 79-Sep 82  

SciTech Connect (OSTI)

An air compressor driven by a wind turbine can be used to operate an air lift water pump. In locations where a shallow aquifer yields a limited quantity of water per unit of time, it is a successful economical method of pumping water for the irrigation of a crop that does not have a critical period of water demand. The amount of submergence of the pumping unit is critical. The efficiency of the system increases as the submergence increases. The efficiency is also dependent upon the proper sizing of the eductor tube. The factors determining the size include submergence, pressure of compressed air, quantity of compressed air available, amount of water lift, and quantity of water required. The rate of air introduced to the eductor tube must be controlled for efficient operation.

Viability of Small Wind Distributed Generation for Farmers Who Irrigate (Poster)  

SciTech Connect (OSTI)

About 14% of U.S. farms are irrigated, representing 55 million acres of irrigated land. Irrigation on these farms is a major energy user in the United States, accounting for one-third of water withdrawals and 137 billion gallons per day. More than half of the Irrigation systems use electric energy. Wind energy can be a good choice for meeting irrigation energy needs. Nine of the top 10 irrigation states (California, Texas, Idaho, Arkansas, Colorado, Nebraska, Arizona, Kansas, Washington, and Oregon) have good to excellent wind resources. Many rural areas have sufficient wind speeds to make wind an attractive alternative, and farms and ranches can often install a wind energy system without impacting their ability to plant crops and graze livestock. Additionally, the rising and uncertain future costs of diesel, natural gas, and even electricity increase the potential effectiveness for wind energy and its predictable and competitive cost. In general, wind-powered electric generation systems generate more energy in the winter months than in the summer months when most crops need the water. Therefore, those states that have a supportive net metering policy can dramatically impact the viability of an onsite wind turbine. This poster presentation highlights case studies that show favorable and unfavorable policies that impact the growth of small wind in this important sector and demonstrate how net metering policies affect the viability of distributed wind generation for farmers who irrigate.

These crops can help supply the transportation sector with agriculturally derived fuels that are cost-competitive with petroleum and do not affect U.S. food supply. PETRO aims to redirect the processes for energy and carbon dioxide (CO2) capture in plants toward fuel production. This would create dedicated energy crops that serve as a domestic alternative to petroleum-based fuels and deliver more energy per acre with less processing prior to the pump.

Electrokinetic pump  

DOE Patents [OSTI]

A method for altering the surface properties of a particle bed. In application, the method pertains particularly to an electrokinetic pump configuration where nanoparticles are bonded to the surface of the stationary phase to alter the surface properties of the stationary phase including the surface area and/or the zeta potential and thus improve the efficiency and operating range of these pumps. By functionalizing the nanoparticles to change the zeta potential the electrokinetic pump is rendered capable of operating with working fluids having pH values that can range from 2-10 generally and acidic working fluids in particular. For applications in which the pump is intended to handle highly acidic solutions latex nanoparticles that are quaternary amine functionalized can be used.

Modeling the Effects of Groundwater-fed Irrigation on Terrestrial Hydrology over the Conterminous United States  

SciTech Connect (OSTI)

Human alteration of the land surface hydrologic cycle is substantial. Recent studies suggest that local water management practices including groundwater pumping and irrigation could significantly alter the quantity and distribution of water in the terrestrial system, with potential impacts on weather and climate through land-atmosphere feedbacks. In this study, we incorporated a groundwater withdrawal scheme into the Community Land Model version 4 (CLM4). To simulate the impact of irrigation realistically, we calibrated the CLM4 simulated irrigation amount against observations from agriculture census at the county scale over the conterminous United States (CONUS). The water used for irrigation was then removed from the surface runoff and groundwater aquifer according to a ratio determined from the county-level agricultural census data. Based on the simulations, the impact of groundwater withdrawals for irrigation on land surface and subsurface fluxes were investigated. Our results suggest that the impacts of irrigation on latent heat flux and potential recharge when water is withdrawn from surface water alone or from both surface and groundwater are comparable and local to the irrigation areas. However, when water is withdrawn from groundwater for irrigation, greater effects on the subsurface water balance were found, leading to significant depletion of groundwater storage in regions with low recharge rate and high groundwater exploitation rate. Our results underscore the importance of local hydrologic feedbacks in governing hydrologic response to anthropogenic change in CLM4 and the need to more realistically simulate the two-way interactions among surface water, groundwater, and atmosphere to better understand the impacts of groundwater pumping on irrigation efficiency and climate.

Energy audit of irrigation networks  

Science Journals Connector (OSTI)

The relationship between water and energy in water distribution systems (WDS) has been a growing concern among energy and water experts. Among the different strategies to improve waterenergy efficiency in water distribution networks, energy audits are of paramount importance as they quantify water flow requirements, the amount of energy consumed to meet demand and leakage and friction losses. Previous work has presented the energy audit process for urban WDS and this energy audit is extended to irrigation networks here. This work analyses the most common types of irrigation emitters (sprinklers and pressure compensating and non-pressure compensating drippers), hydrant specifications, irrigation management systems (on-demand or rigid scheduled), and energy losses due to friction in pipes, control valves and irrigation hydrants. The energy audit does not assess whether management of the network is optimal, but analyses the energy consumption. Some of the performance indicators have already been defined for agricultural water networks, some are identical to those of urban WDS, but in addition, a new one is presented that disaggregates the energy dissipated into three terms, energy losses in pipelines, in hydraulic valves and in irrigation hydrants. These indicators show information necessary to better understand the performance of the irrigation network under study, to carry out a deep analysis of energy consumption and to allow for comparison with similar systems. The paper presents the analysis of a real case study conducted on the irrigation network of the garden of the Universidad Politcnica de Valencia.

Chapter 9 - Hydraulic Pumps  

Science Journals Connector (OSTI)

Publisher Summary This chapter provides an overview of hydraulic-powered downhole pumps, which are powered by a stream of high pressure power fluid supplied by a power fluid (PF) pump at the surface and sent to a downhole pump or pump engine. Hydraulic pumps are basically of two typespiston downhole pumps that are similar to beam down-hole pumps, and jet downhole pumps that reduce the pressure on the formation by high-speed power fluid flow through the throat of a venturi or jet pump nozzle-diffuser combination. Hydraulic pumps can be used to remove liquids from gas wells. A skid-mounted hydraulic pump can be used to kick off a gas well and then be moved to another well for testing, production, or longer term de-watering. Hydraulic pumping is generally not depth limited, and deviated or crooked wells do not present problems. Hydraulic reciprocating pumps can produce a low bottomhole pressure. A jet pump may require a fluid height over the pump of 20% of submergence. A jet pump is more trouble-free than a reciprocating hydraulic pump and can tolerate some solids in the production. Fairly high rates of more than several hundred bbls/day are possible. In general, hydraulic systems are not rate limited when removing liquids from gas wells.

Measuring Transpiration to Regulate Winter Irrigation Rates  

SciTech Connect (OSTI)

Periodic transpiration (monthly sums) in a young loblolly pine plantation between ages 3 and 6 was measured using thermal dissipation probes. Fertilization and fertilization with irrigation were better than irrigation alone in increasing transpiration of young loblolly pines during winter months, apparently because of increased leaf area in fertilized trees. Irrigation alone did not significantly increase transpiration compared with the non-fertilized and non-irrigated control plots.

Alternative backing up pump for turbomolecular pumps  

DOE Patents [OSTI]

As an alternative to the use of a mechanical backing pump in the application of wide range turbomolecular pumps in ultra-high and extra high vacuum applications, palladium oxide is used to convert hydrogen present in the evacuation stream and related volumes to water with the water then being cryo-pumped to a low pressure of below about 1.e.sup.-3 Torr at 150.degree. K. Cryo-pumping is achieved using a low cost Kleemenco cycle cryocooler, a somewhat more expensive thermoelectric cooler, a Venturi cooler or a similar device to achieve the required minimization of hydrogen partial pressure.

Optimal Quantum Pumps  

E-Print Network [OSTI]

We study adiabatic quantum pumps on time scales that are short relative to the cycle of the pump. In this regime the pump is characterized by the matrix of energy shift which we introduce as the dual to Wigner's time delay. The energy shift determines the charge transport, the dissipation, the noise and the entropy production. We prove a general lower bound on dissipation in a quantum channel and define optimal pumps as those that saturate the bound. We give a geometric characterization of optimal pumps and show that they are noiseless and transport integral charge in a cycle. Finally we discuss an example of an optimal pump related to the Hall effect.

Water Use Efficiency, Irrigation Management and Nitrogen Utilization in Rice Production in the North of Iran  

Science Journals Connector (OSTI)

Abstract Iran with nearly 165 million hectare of land area and amount of rainfall equal to 300mm in 67% of its territorial land, is considered as a semi-dry region in the world. Rice production in Iran needs to be increased to feed a growing population, whereas water for irrigation is getting scarce. One way to decrease water consumption in paddy field is the change of irrigation regime and replacement of continuous submergence to alternate submergence. In order to investigate the effect of different regimes of irrigation and nitrogen fertilizer on yield of hybrid rice, an experiment was conducted at the Rice Research Institute of Iran during crop season 2008. The experiment was arranged in split plot based on completely randomized block design with 3 replications in which water regimes were main factor included continuous submergence and alternately submergence (irrigation intervals of 5, 8 and 11days) and nitrogen fertilizer levels were sub factor included 0, 90, 120 and 150kg/ha. Grain yield,water use efficiency,relative water content,total nitrogen,grain nitrogen and nitrogen harvest index were statistically the same under continuous submergence and irrigation interval of 5 and 8 days and were lowest in 11- day interval.total nitrogen,grain nitrogen and nitrogen harvest index decreased with the increment of nitrogen.we concluded that 8- day interval could reduce water consumption in paddy fields in the North of Iran.

Redesign of turbine-pump impeller and diffuser using hydrodynamic design techniques. Final report  

SciTech Connect (OSTI)

It is indicated that in 1976 the average operating efficiency of well irrigation pumps in the US, including losses in the column pipe and line shaft, was 55.5%, but information is presented to show that losses in a pumping system can be reduced and that it is possible to reach a goal of 82% system efficiency. Hydrodynamic design methods which are used to analyze and modify a commercially available pump are presented. The results of tests with the pump are presented for which delivery losses were reduced by means of a packer at the pump and for which line shaft losses were reduced by means of a high strength line shaft. Methods of designing pumps that have a broader high efficiency range are explored, and a design approach for doing so is presented. The method was not evaluated experimentally. (MCW)

Liquid metal electric pump  

DOE Patents [OSTI]

An electrical pump for pumping liquid metals to high pressures in high temperature environments without the use of magnets or moving mechanical parts. The pump employs a non-porous solid electrolyte membrane, typically ceramic, specific to the liquid metal to be pumped. A DC voltage is applied across the thickness of the membrane causing ions to form and enter the membrane on the electrically positive surface, with the ions being neutralized on the opposite surface. This action provides pumping of the liquid metal from one side of the non-porous solid electrolyte membrane to the other. 3 figs.

NREL: Learning - Pumped Hydropower  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

Pumped Hydropower Pumped Hydropower Pumped hydro facilities use off-peak electricity to pump water from a lower reservoir into one at a higher elevation. When the water stored in the upper reservoir is released, it is passed through hydraulic turbines to generate electricity. The off-peak electrical energy used to pump the water up hill can be stored indefinitely as gravitational energy in the upper reservoir. Thus, two reservoirs in combination can be used to store electrical energy for a long period of time, and in large quantities. Utilities generally prefer to operate large coal and nuclear power stations at full power all the time (referred to as "baseload generation"), so in the middle of the night, these plants often produce more power than is needed. Pumped hydro energy storage can be used to smooth out the demand

Radioactivity in food crops  

SciTech Connect (OSTI)

Published levels of radioactivity in food crops from 21 countries and 4 island chains of Oceania are listed. The tabulation includes more than 3000 examples of 100 different crops. Data are arranged alphabetically by food crop and geographical origin. The sampling date, nuclide measured, mean radioactivity, range of radioactivities, sample basis, number of samples analyzed, and bibliographic citation are given for each entry, when available. Analyses were reported most frequently for /sup 137/Cs, /sup 40/K, /sup 90/Sr, /sup 226/Ra, /sup 228/Ra, plutonium, uranium, total alpha, and total beta, but a few authors also reported data for /sup 241/Am, /sup 7/Be, /sup 60/Co, /sup 55/Fe, /sup 3/H, /sup 131/I, /sup 54/Mn, /sup 95/Nb, /sup 210/Pb, /sup 210/Po, /sup 106/Ru, /sup 125/Sb, /sup 228/Th, /sup 232/Th, and /sup 95/Zr. Based on the reported data it appears that radioactivity from alpha emitters in food crops is usually low, on the order of 0.1 Bq.g/sup -1/ (wet weight) or less. Reported values of beta radiation in a given crop generally appear to be several orders of magnitude greater than those of alpha emitters. The most striking aspect of the data is the great range of radioactivity reported for a given nuclide in similar food crops with different geographical origins.

Quantum pumping in graphene  

Science Journals Connector (OSTI)

We show that graphene-based quantum pumps can tap into evanescent modes, which penetrate deeply into the device as a consequence of Klein tunneling. The evanescent modes dominate pumping at the Dirac point, and give rise to a universal response under weak driving for short and wide pumps, in close analogy to their role in the minimal conductivity in ballistic transport. In contrast, evanescent modes contribute negligibly to normal pumps. Our findings add an incentive for the exploration of graphene-based nanoelectronic devices.

Chapter 9 - Hydraulic pumping  

Science Journals Connector (OSTI)

Publisher Summary The hydraulic pumping system takes liquid (water or oil) from a liquid reservoir on the surface, puts it through a reciprocating multiplex piston pump or horizontal electrical submersible pump to increase the pressure, and then injects the pressurized liquid (power fluid) down-hole through a tubing string. At the bottom of the injection tubing string, the power fluid is directed into the nozzle of a jet pump or to the hydraulic engine of a piston pump, both of which have been set well below the producing fluid level. The surface injection pressures normally range from approximately 2000 psi up to 4000 psi, with some going up to but rarely above 4500 psi. An electric motor, diesel engine, or gas engine is used to drive the multiplex pump. The fundamental operating principle of subsurface hydraulic pumps is Pascal's Law, postulated by Blaise Pascal in 1653. This principle makes it possible to transmit pressure from the surface by means of a liquid-filled tubing string to any given point below the surface. The chapter further highlights applications to dewatering wells-gas and coal bed methane, limitations of other forms of lift, advantages of hydraulic pumping, disadvantages of hydraulic pumping, and different types of operating systems.

Energy characterisation of herbaceous biomasses irrigated with marginal waters  

Science Journals Connector (OSTI)

Abstract The paper reports the results of a research program aiming to evaluate the agronomic, and energy sustainability of the biomass production by perennial non-food herbaceous crops irrigated with different kinds of marginal waters. In four different sites (Bologna, Padova, Reggio Calabria, and Catania) the same four species (Arundo, Typha, Phragmites, and Lythrum), usually tested without irrigation, were planted and monitored during 20082010. The results show that a planting density of 10m?2 is necessary to obtain a maximum dry yield levels already from the second year of transplanting. The maximum productivity was obtained with Arundo (close to 100Mgha?1y?1 in Bologna and 86Mgha?1y?1 in Padova, 5060Mgha?1y?1 in the southern locations). Lythrum productivity ranged from 5.2 to 9.2Mgha?1y?1 in all the RUs, with the exception of Reggio Calabria. Typha (around 10Mgha?1y?1 at the third year) and Phragmites (58Mgha?1y?1) gave significant production only in the northern locations. The \\{HHVs\\} were close to 15.5MJkg?1 for Phragmites (except for Catania and Reggio Calabria with 20.0MJkg?1) 18.0MJkg?1 for the Arundo (except for Catania with 20.0MJkg?1), 18.5MJkg?1 for the Typha and Lythrum (except for Catania with 20.0MJkg?1).

Underground pumped hydroelectric storage  

SciTech Connect (OSTI)

Underground pumped hydroelectric energy storage was conceived as a modification of surface pumped storage to eliminate dependence upon fortuitous topography, provide higher hydraulic heads, and reduce environmental concerns. A UPHS plant offers substantial savings in investment cost over coal-fired cycling plants and savings in system production costs over gas turbines. Potential location near load centers lowers transmission costs and line losses. Environmental impact is less than that for a coal-fired cycling plant. The inherent benefits include those of all pumped storage (i.e., rapid load response, emergency capacity, improvement in efficiency as pumps improve, and capacity for voltage regulation). A UPHS plant would be powered by either a coal-fired or nuclear baseload plant. The economic capacity of a UPHS plant would be in the range of 1000 to 3000 MW. This storage level is compatible with the load-leveling requirements of a greater metropolitan area with population of 1 million or more. The technical feasibility of UPHS depends upon excavation of a subterranean powerhouse cavern and reservoir caverns within a competent, impervious rock formation, and upon selection of reliable and efficient turbomachinery - pump-turbines and motor-generators - all remotely operable.

Fluid pumping apparatus  

DOE Patents [OSTI]

A method and apparatus suitable for coupling seismic or other downhole sensors to a borehole wall in high temperature and pressure environments. In one embodiment, one or more metal bellows mounted to a sensor module are inflated to clamp the sensor module within the borehole and couple an associated seismic sensor to a borehole wall. Once the sensing operation is complete, the bellows are deflated and the sensor module is unclamped by deflation of the metal bellows. In a further embodiment, a magnetic drive pump in a pump module is used to supply fluid pressure for inflating the metal bellows using borehole fluid or fluid from a reservoir. The pump includes a magnetic drive motor configured with a rotor assembly to be exposed to borehole fluid pressure including a rotatable armature for driving an impeller and an associated coil under control of electronics isolated from borehole pressure.

Best Management Practice: Water-Efficient Irrigation | Department of Energy  

Broader source: Energy.gov (indexed) [DOE]

Irrigation Irrigation Best Management Practice: Water-Efficient Irrigation October 7, 2013 - 3:10pm Addthis Water efficiency must be considered from the initial irrigation system design phase through installation to ensure optimal performance. Consistent management and maintenance is also essential. Failure to do so can result in losing more than 50% of irrigation water due to evaporation, wind, poor management, and/or improper system design, installation, or maintenance. With the irrigation system hardware operating efficiently, it is important to consider the irrigation schedule, which dictates the amount and timing of the water applied. Water changes with the seasons as should your irrigation schedule. Many landscapes are watered at the same level all year, adding unnecessary water for months at a time. Over-watering can

Molecular heat pump  

E-Print Network [OSTI]

We propose a novel molecular device that pumps heat against a thermal gradient. The system consists of a molecular element connecting two thermal reservoirs that are characterized by different spectral properties. The pumping action is achieved by applying an external force that periodically modulates molecular levels. This modulation affects periodic oscillations of the internal temperature of the molecule and the strength of its coupling to each reservoir resulting in a net heat flow in the desired direction. The heat flow is examined in the slow and fast modulation limits and for different modulation waveforms, thus making it possible to optimize the device performance.

Indexes of pumps for oil field pumping units  

SciTech Connect (OSTI)

As reported previously, a series of oil field pumping units has been developed with power outputs of 125, 250, 500, and 1000 kW, designed for injecting working fluids in cementing operations in oil and gas wells, hydraulic fracturing of formations, washing out sand plugs, and other production operations. The units are designed for the use of three-plunger pumps with individual power outputs of 125 or 500 kW. In the 250- and 1000-kW units, two such pumps are used. The 1000-kW pumping unit serves mainly for deep-penetration hydraulic fracturing of formations, and also for fracturing deep formations. The hydraulic fracturing process does not require the use of units with two pumps; this has been demonstrated by experience, both here and in other countries. All units intended for use in hydraulic fracturing are built with a single pump, transmission, and drive. Pumping units for well cementing must have two pumps that will give a high delivery rate. At the start of the operation, a single pump can be used to feed water into the cement mixer, with the second pump used to transfer the cement slurry to the well. Then both pumps are connected to the slurry injection line. The operation of these pumps is described.

Optical pumping of ions  

Science Journals Connector (OSTI)

Radiofrequency spectroscopy has been extended to positive ions with S ground states by means of optical pumping. The ions are stored in buffer gases or ion traps and are polarized directly by optical pumping or indirectly by spin exchange, change exchange, or Penning ionization with optically pumped atoms. The applied methods are described. The experiments can be divided into two categories: Collisional interactions of the polarized ions are investigated, like the exchange processes mentioned above, spin exchange with free electrons, spin depolarization and hyperfine density shifts in rare gases. For the two latter effects drastic differences are observed between atomic and ionic 2S12 states the explanations of which reveal the influence of the ionic charge on the interactions. The comparison of equivalent processes involving isoelectronic 2S or 2P configurations of atoms and ions provides a test of current collision theories. Precision rf spectroscopy of ionic ground states yields the 2S12 hyperfine structure splittings of 3He+ and group II ions with relative accuracies of up to 10?9, with further improvement possible. Direct and indirect optical pumping of 1S0 ions is used to determine nuclear magnetic moments, diamagnetic shielding coefficients, and chemical shifts. Applications and further developments of the present methods are discussed.

LCA of cropping systems with different external input levels for energetic purposes  

Science Journals Connector (OSTI)

Biofuels could become increasingly important for agriculture; however there is growing concern regarding the possible environmental drawbacks due to the risks of increased inputs during crop cultivation. These risks need to be evaluated in order to assess the best management practices. In this study, a life cycle assessment (LCA) was carried out: (i) to evaluate the environmental impacts of three cropping systems characterized by different external input levels (low S1, medium S2 and high S3) applied to sunflower and maize, both in rotation with wheat, in a Mediterranean region; (ii) to estimate the environmental benefits of the optimization of cropping systems for energy management. Outputinput ratio, net energy balance, global warming potential (GWP), eutrophication potential (EP) and acidification potential (AP) were used as LCA impact categories. Data from cropping systems (external input and crop yields) were collected from a long-term experiment carried out in the coastal plain of Tuscany; data regarding fertilizers, machinery and pesticide production were taken from literature. The results obtained showed S1 with the highest outputinput ratios and the lowest impact for the selected impact categories. The other cropping systems S2 and S3 showed limited differences between them for all the impact categories evaluated. Fertilizer use and application, irrigation and machinery use caused most of the environmental impacts and energy consumption. The allocation procedure, showing residues as co-products, had a strong influence on the overall efficiency of agricultural systems.

Water displacement mercury pump  

DOE Patents [OSTI]

A water displacement mercury pump has a fluid inlet conduit and diffuser, a valve, a pressure cannister, and a fluid outlet conduit. The valve has a valve head which seats in an opening in the cannister. The entire assembly is readily insertable into a process vessel which produces mercury as a product. As the mercury settles, it flows into the opening in the cannister displacing lighter material. When the valve is in a closed position, the pressure cannister is sealed except for the fluid inlet conduit and the fluid outlet conduit. Introduction of a lighter fluid into the cannister will act to displace a heavier fluid from the cannister via the fluid outlet conduit. The entire pump assembly penetrates only a top wall of the process vessel, and not the sides or the bottom wall of the process vessel. This insures a leak-proof environment and is especially suitable for processing of hazardous materials.

Charge Pumping in Carbon Nanotubes  

Science Journals Connector (OSTI)

We demonstrate charge pumping in semiconducting carbon nanotubes by a traveling potential wave. From the observation of pumping in the nanotube insulating state we deduce that transport occurs by packets of charge being carried along by the wave. By tuning the potential of a side gate, transport of either electron or hole packets can be realized. Prospects for the realization of nanotube based single-electron pumps are discussed.

Chemical heat pump  

DOE Patents [OSTI]

A chemical heat pump system is disclosed for use in heating and cooling structures such as residences or commercial buildings. The system is particularly adapted to utilizing solar energy, but also increases the efficiency of other forms of thermal energy when solar energy is not available. When solar energy is not available for relatively short periods of time, the heat storage capacity of the chemical heat pump is utilized to heat the structure, as during nighttime hours. The design also permits home heating from solar energy when the sun is shining. The entire system may be conveniently rooftop located. In order to faciliate installation on existing structures, the absorber and vaporizer portions of the system may each be designed as flat, thin wall, thin pan vessels which materially increase the surface area available for heat transfer. In addition, this thin, flat configuration of the absorber and its thin walled (and therefore relatively flexible) construction permits substantial expansion and contraction of the absorber material during vaporization and absorption without generating voids which would interfere with heat transfer.

Heat Pump Market in Thailand  

Science Journals Connector (OSTI)

The value of hot water system in Thailand, rarely mentioned or quantified, is almost 3,000 million Baht per year. The heat pump is an option of hot water system. The development of heat pump in Thailand is officially started in 2002 according to the program of subsidy for heat pump but before that there was some slow development. Comparing to the cost of hot water production from instantaneous system, local manufactured heat pump is commercial viable even without the subsidy. The imported heat pump compared to local production can be sold to only high end user or high awareness of energy. The important factor of heat pump development is depended on the selling price, performance, and the customer behavior. The highest efficiency may not be the winner in Thai market as the drivers for higher efficiency or co-efficiency of performance of heat pump is not so strong compared to the price. Some of information in this paper cannot be supported by the real data because of the brand name of heat pump cannot be published.

Solar pumping installation for pumping liquid and solar collector construction  

SciTech Connect (OSTI)

A solar pumping system, comprises, a pumping housing which defines a pump chamber therein which is adapted to be positioned in the ground below ground water level. Displacer means in the form of, for example, a bladder, arranged within the pump chamber, is capable of displacing liquid out of the pump chamber in response to a pressurized medium acting thereon to expel the water out of the chamber and up to a level above the ground for use. A suction valve connected into the chamber permits the ground water to flow into the chamber and a discharge valve connected out of the chamber permits the outflow of the ground water during the action of the displacer means. The construction includes a solar collector having at least one hydride conduit which is adapted to be exposed to the sun for solar heating to act on the hydride to cause hydrogen to be formed, the pressure of which acts against the displacer means to displace the ground liquid out of the pump chamber. When the solar collector is shielded and the hydride is permitted to cool or is cooled rapidly by the circulation of water thereover, the pressure of the generated hydrogen decreases, permitting ground water to enter into the pumping chamber once again through the suction valves.

Estimates of Savings Achievable from Irrigation Controller  

SciTech Connect (OSTI)

This paper performs a literature review and meta-analysis of water savings from several types of advanced irrigation controllers: rain sensors (RS), weather-based irrigation controllers (WBIC), and soil moisture sensors (SMS).The purpose of this work is to derive average water savings per controller type, based to the extent possible on all available data. After a preliminary data scrubbing, we utilized a series of analytical filters to develop our best estimate of average savings. We applied filters to remove data that might bias the sample such as data self-reported by manufacturers, data resulting from studies focusing on high-water users, or data presented in a non-comparable format such as based on total household water use instead of outdoor water use. Because the resulting number of studies was too small to be statistically significant when broken down by controller type, this paper represents a survey and synthesis of available data rather than a definitive statement regarding whether the estimated water savings are representative.

Chapter 13 - Progressing cavity pumps  

Science Journals Connector (OSTI)

Publisher Summary Progressing cavity pumps (PCPs) have the advantage of being able to easily pump solids, liquids, and gasses. With comparatively the lowest capital cost and highest operating efficiencies of any ALS, \\{PCPs\\} are the preferred artificial lift system for many CBM operations. Dewatering CBM wells with \\{PCPs\\} is a relatively routine operation that has been deployed successfully since the mid-1980s. The PC pump is composed of two components, the rotor and the stator. The rotor is manufactured from high strength steel and covered with a chrome layer 0.010 to 0.020 inches thick. The rotor is the only moving component of the pump. The stator has an internal helix shape molded into an elastomer compound that is chemically bonded to the inside of a steel tube. When the rotor is inserted into the stator, it creates a continuous seal line (compression/interference fit between the rotor and stator elastomer) that extends from the pump suction to discharge. This creates a series of identical, but separate, cavities that progress from the pump suction to the discharge as the rotor turns. Water production handling, gas production handling, critical tubing flow velocity, and pump landing depth are briefly discussed in this chapter

Electromagnetically driven peristaltic pump  

DOE Patents [OSTI]

An electromagnetic peristaltic pump apparatus may comprise a main body section having an inlet end and an outlet end and a flexible membrane which divides the main body section into a first cavity and a second cavity. The first cavity is in fluid communication with the inlet and outlet ends of the main body section. The second cavity is not in fluid communication with the first cavity and contains an electrically conductive fluid. The second cavity includes a plurality of electrodes which are positioned within the second cavity generally adjacent the flexible membrane. A magnetic field generator produces a magnetic field having a plurality of flux lines at least some of which are contained within the second cavity of the main body section and which are oriented generally parallel to a flow direction in which a material flows between the inlet and outlet ends of the main body section. A control system selectively places a voltage potential across selected ones of the plurality of electrodes to deflect the flexible membrane in a wave-like manner to move material contained in the first cavity between the inlet and outlet ends of the main body section.

Broader source: Energy.gov (indexed) [DOE]

heat pump-like an air conditioner or refrigera- heat pump-like an air conditioner or refrigera- tor-moves heat from one place to another. In the summer, a geothermal heat pump (GHP) operating in a cooling mode lowers indoor temperatures by transferring heat from inside a building to the ground outside or below it. Unlike an air condition- er, though, a heat pump's process can be reversed. In the winter, a GHP extracts heat from the ground and transfers it inside. Also, the GHP can use waste heat from summer air-conditioning to provide virtually free hot-water heating. The energy value of the heat moved is typically more than three times the electricity used in the transfer process. GHPs are efficient and require no backup heat because the earth stays at a relatively moderate temperature throughout the year.

Method for controlling powertrain pumps  

DOE Patents [OSTI]

A method of controlling a pump supplying a fluid to a transmission includes sensing a requested power and an excess power for a powertrain. The requested power substantially meets the needs of the powertrain, while the excess power is not part of the requested power. The method includes sensing a triggering condition in response to the ability to convert the excess power into heat in the transmission, and determining that an operating temperature of the transmission is below a maximum. The method also includes determining a calibrated baseline and a dissipation command for the pump. The calibrated baseline command is configured to supply the fluid based upon the requested power, and the dissipation command is configured to supply additional fluid and consume the excess power with the pump. The method operates the pump at a combined command, which is equal to the calibrated baseline command plus the dissipation command.

Microelectromechanical pump utilizing porous silicon  

DOE Patents [OSTI]

A microelectromechanical (MEM) pump is disclosed which includes a porous silicon region sandwiched between an inlet chamber and an outlet chamber. The porous silicon region is formed in a silicon substrate and contains a number of pores extending between the inlet and outlet chambers, with each pore having a cross-section dimension about equal to or smaller than a mean free path of a gas being pumped. A thermal gradient is provided along the length of each pore by a heat source which can be an electrical resistance heater or an integrated circuit (IC). A channel can be formed through the silicon substrate so that inlet and outlet ports can be formed on the same side of the substrate, or so that multiple MEM pumps can be connected in series to form a multi-stage MEM pump. The MEM pump has applications for use in gas-phase MEM chemical analysis systems, and can also be used for passive cooling of ICs.

Comparative evaluation of crop water use efficiency, economic analysis and net household profit simulation in arid Northwest China  

Science Journals Connector (OSTI)

Abstract Decreasing water availability for agricultural production has prompted researchers to focus on comparing and evaluating water use efficiency (WUE) of different crops in various water management strategies. A field survey was conducted to investigate the amount of irrigation water, inputs and yields of eight crops (spring wheat, maize, onion, cotton, hot pepper, sunflower, melons and fennel) grown under furrow irrigation systems in an arid region, Minqin county, Northwestern China (NWC). Previous publications reporting crop WUE were identified and major statistics of evapotranspiration (ET), yield (Y) and WUE were calculated for each crop. By comparing with literature reporting, the mean WUE of onion (8.71kgm?3), cotton (0.56kgm?3), sunflower seed (0.78kgm?3) and fennel (0.51kgm?3) grown in NWC were at the same high levels; while WUE of wheat (0.87kgm?3) and maize (1.17kgm?3) were slightly lower and WUE of hot pepper (2.68kgm?3) and melons (3.27kgm?3) were extremely low. Great potential of saving water could be achieved to realize increased or ideal WUE values for crops in NWC. The total net profit per household of cotton (1606.62$hh?1) was significantly larger and of onion (?3132.30$hh?1) significantly lower than that of other crops. Cotton, sunflower seed, melons and hot pepper had significantly higher crop production values per unit water than other crops, 0.39$m?3, 0.36$m?3, 0.32$m?3 and 0.31$m?3, respectively. The net household profits were significantly higher when excluding onion production for its extremely low price in 2011. With simulation based on different combinations of onion production and increase of migrant workers, the average net household profit could be optimized to provide benefits to local farmers and policy makers regarding income increase and rural policy design.

Fitting fertilisation in LCA: allocation to crops in a cropping plan  

Science Journals Connector (OSTI)

This article reflects some results of a study on life cycle assessment (LCA) for agricultural products, concerning specific features of agricultural production. Attention is given to the cultivation of crops in a crop rotation and the role of fertilisation. When carrying out an LCA for a single agricultural product one should be aware of the fact that arable crops are usually grown in a crop rotation system. So, it is important to show the cropping plan and to identify all activities that may be meant to benefit more than one crop, like fertilisation with phosphate, potassium and organic matter. Environmental impacts of the application of phosphate and potassium should be allocated to the crops according to the uptake and uptake efficiency per crop. Impacts caused by fertilisation with organic matter should be allocated according to the land use per crop.

Optical pumping and xenon NMR  

SciTech Connect (OSTI)

Nuclear Magnetic Resonance (NMR) spectroscopy of xenon has become an important tool for investigating a wide variety of materials, especially those with high surface area. The sensitivity of its chemical shift to environment, and its chemical inertness and adsorption properties make xenon a particularly useful NMR probe. This work discusses the application of optical pumping to enhance the sensitivity of xenon NMR experiments, thereby allowing them to be used in the study of systems with lower surface area. A novel method of optically-pumping [sup 129]Xe in low magnetic field below an NMR spectrometer and subsequent transfer of the gas to high magnetic field is described. NMR studies of the highly polarized gas adsorbed onto powdered samples with low to moderate surface areas are now possible. For instance, NMR studies of optically-pumped xenon adsorbed onto polyacrylic acid show that xenon has a large interaction with the surface. By modeling the low temperature data in terms of a sticking probability and the gas phase xenon-xenon interaction, the diffusion coefficient for xenon at the surface of the polymer is determined. The sensitivity enhancement afforded by optical pumping also allows the NMR observation of xenon thin films frozen onto the inner surfaces of different sample cells. The geometry of the thin films results in interesting line shapes that are due to the bulk magnetic susceptibility of xenon. Experiments are also described that combine optical pumping with optical detection for high sensitivity in low magnetic field to observe the quadrupoler evolution of 131 Xe spins at the surface of the pumping cells. In cells with macroscopic asymmetry, a residual quadrupolar interaction causes a splitting in the [sup 131]Xe NMR frequencies in bare Pyrex glass cells and cells with added hydrogen.

Recycling of domestic wastewater treated by vertical-flow wetlands for irrigating Chillies and Sweet Peppers  

Science Journals Connector (OSTI)

Abstract Due to water scarcity in many arid countries, there is considerable interest in recycling various wastewater streams such as treated urban wastewater for irrigation in the agricultural sector. The aim was therefore to assess if domestic wastewater treated by different wetlands can be successfully recycled to water commercially grown crops. The objectives were to assess variables and boundary conditions impacting on the growth of two different types of peppers fed by domestic wastewater pre-treated by diverse mature constructed treatment wetlands. The growth of both Sweet Pepper (California Wonder; cultivar of Capsicum annuum Linnaeus Grossum Group) and Chilli (De Cayenne; C. annuum (Linnaeus) Longum Group De Cayenne) fed with different treated and untreated wastewater types were assessed. A few plants suffered from either a shortage and/or excess of some nutrients and trace minerals. The overall growth development of Sweet Peppers was poor due to the high concentrations of nutrients and trace minerals. In contrast, Chilies did reasonably well, but the growth of foliage was excessive and the harvest was delayed. High yields were associated with tap water and an organic growth medium, and a wetland with a high aggregate size, leaving sufficient space for biomass. Low fruit numbers correlated well with inorganic growth media and irrigation water contaminated by hydrocarbons. Findings indicate that nutrient concentrations supplied to the Chillies by a combination of compost and treated waste water are usually too high to produce a good harvest. However, as the compost is depleted of nutrients after about eight months, the harvest increased for pots that received pre-treated wastewater. The project contributes to ecological sanitation understanding by closing the loop in the food and water chain.

FED pumped limiter configuration issues  

SciTech Connect (OSTI)

Impurity control in the Fusion Engineering Device (FED) is provided by a toroidal belt pumped limiter. Limiter design issues addressed in this paper are (1) poloidal location of the limiter belt, (2) shape of the limiter surface facing the plasma, and (3) whether the belt is pumped from one or both sides. The criteria used for evaluation of limiter configuration features were sensitivity to plasma-edge conditions and ease of maintenance and fabrication. The evaluation resulted in the selection of a baseline FED limiter that is located at the bottom of the device and has a flat surface with a single leading edge.

Peristaltic pumps work in nano scales  

E-Print Network [OSTI]

A design for a pump is suggested which is based on well-known peristaltic pumps. In order to simply describe the operation of the proposed pump, an innovative interpretation of low Reynolds number swimmers is presented and thereafter a similar theoretical model would be suggested to quantify the behavior of the pumps. A coarse-grained molecular dynamic simulation is used to examine the theoretical predictions and measure the efficiency of the pump in nano scales. It is shown that this pump with a modest design is capable of being a good option for transport processes in nano scale.

Electric field divertor plasma pump  

DOE Patents [OSTI]

An electric field plasma pump includes a toroidal ring bias electrode (56) positioned near the divertor strike point of a poloidal divertor of a tokamak (20), or similar plasma-confining apparatus. For optimum plasma pumping, the separatrix (40) of the poloidal divertor contacts the ring electrode (56), which then also acts as a divertor plate. A plenum (54) or other duct near the electrode (56) includes an entrance aperture open to receive electrically-driven plasma. The electrode (56) is insulated laterally with insulators (63,64), one of which (64) is positioned opposite the electrode at the entrance aperture. An electric field E is established between the ring electrode (56) and a vacuum vessel wall (22), with the polarity of the bias applied to the electrode being relative to the vessel wall selected such that the resultant electric field E interacts with the magnetic field B already existing in the tokamak to create an E.times.B/B.sup.2 drift velocity that drives plasma into the entrance aperture. The pumped plasma flow into the entrance aperture is insensitive to variations, intentional or otherwise, of the pump and divertor geometry. Pressure buildups in the plenum or duct connected to the entrance aperture in excess of 10 mtorr are achievable.

How does it work? A geothermal heat pump uses the constant below ground temperature of soil or water to heat and cool your home. Geothermal heat pumps (GHPs), sometimes referred to as GeoExchange, earth-coupled, ground-source, or water-source heat pumps, have been in use since the late 1940s. They use the constant temperature of the earth as the exchange medium instead of the outside air temperature. This allows the system to reach fairly high efficiencies (300% to 600%) on the coldest winter nights, compared to 175% to 250% for air-source heat pumps on cool

Fruit Yield and Quality, and Irrigation Water Use Efficiency of Summer Squash Drip-Irrigated with Different Irrigation Quantities in a Semi-Arid Agricultural Area  

Science Journals Connector (OSTI)

Abstract Fruit yield, yield components, fruit mineral content, total phenolic content, antioxidant activity and irrigation water use efficiency (IWUE) of summer squash responses to different irrigation quantities were evaluated with a field study. Irrigations were done when the total evaporated water from a Class A pan was about 30 mm. Different irrigation quantities were adjusted using three different plant-pan coefficients (Kcp, 100% (Kcp1), 85% (Kcp2) and 70% (Kcp3)). Results indicated that lower irrigation quantities provided statistically lower yield and yield components. The highest seasonal fruit yield (80.0 t ha?1) was determined in the Kcp1 treatment, which applied the highest volume of irrigation water (452.9 mm). The highest early fruit yield, average fruit weight and fruit diameter, length and number per plant were also determined in the Kcp1 treatment, with values of 7.25 t ha?1, 264.1 g, 5.49 cm, 19.95 cm and 10.92, respectively. Although the IWUE value was the highest in the Kcp1 treatment (176.6 kg ha?1 mm?1), it was statistically similar to the value for Kcp3 treatment (157.1 kg ha?1 mm?1). Total phenolic content and antioxidant activity of fruits was higher in the Kcp1 (44.27 ?g gallic acid equivalents (GAE) mg?1 fresh sample) and in the Kcp2 (84.75%) treatments, respectively. Major (Na, N, P, K, Ca, Mg and S) and trace (Fe, Cu, Mn, Zn and B) mineral contents of squash fruits were the highest in the Kcp2 treatment, with the exception of P, Ca and Cu. Mineral contents and total phenolic content were significantly affected by irrigation quantities, but antioxidant activity was not affected. It can be concluded that the Kcp1 treatment was the most suitable for achieving higher yield and IWUE. However, the Kcp2 treatment will be the most suitable due to the high fruit quality and relatively high yield in water shortage conditions.

Short rotation Wood Crops Program  

SciTech Connect (OSTI)

This report synthesizes the technical progress of research projects in the Short Rotation Woody Crops Program for the year ending September 30, 1989. The primary goal of this research program, sponsored by the US Department of Energy's Biofuels and Municipal Waste Technology Division, is the development of a viable technology for producing renewable feedstocks for conversion to biofuels. One of the more significant accomplishments was the documentation that short-rotation woody crops total delivered costs could be $40/Mg or less under optimistic but attainable conditions. By taking advantage of federal subsidies such as those offered under the Conservation Reserve Program, wood energy feedstock costs could be lower. Genetic improvement studies are broadening species performance within geographic regions and under less-than-optimum site conditions. Advances in physiological research are identifying key characteristics of species productivity and response to nutrient applications. Recent developments utilizing biotechnology have achieved success in cell and tissue culture, somaclonal variation, and gene-insertion studies. Productivity gains have been realized with advanced cultural studies of spacing, coppice, and mixed-species trials. 8 figs., 20 tabs.

Report on New Pumping System Software on Pumping Instrumentation and Control Skids  

SciTech Connect (OSTI)

This report documents the details of the Programmable Logic Controller (PLC) and the Data Table Access Module (DTAM) logic developed for the new pumping system employed for saltwell pumping. The new system is planned first for pumping A-101 where Pumping Instrumentation and Control (PIC) skid ''F'' is located. The new pump requires a bump start under certain conditions that will be controlled by the PLC. The bump start is to ensure sufficient water to the pump bearing cavities. The PLC logic is required to control the shutdown of the injection pump that supplies the water to the saltwell pump bearing cavities. Allowance to start and stop the injection pump will be controlled by the PLC at the PIC skid. This report is written for PIC skid ''P'', but will apply to other PIC skids where the new pumping system is deployed. The logic will remain the same, but the ladder rung-numbers may change from skid to skid.

Integrated assessment of Hadley Center (HadCM2) climate-change impacts on agricultural productivity and irrigation water supply in the conterminous United States: Part II. Regional agricultural production in 2030 and 2095  

Science Journals Connector (OSTI)

A national assessment (NA) evaluated the potential consequences of climate change and variability on the agriculture, water resources, as well as other economic and natural resource sectors in the United States. As part of this process, we used scenarios of the HadCM2 GCM and the EPIC agroecosystem model to evaluate climate-change impacts on crop yields and ecosystem processes. Baseline climate data were obtained from national records for 19611990. The scenario runs for 20252034 and 20902099 were extracted from a HadCM2 run. EPIC was run on 204 representative farms under current climate and two 10-year periods centered on 2030 and 2095, each at CO2 concentrations of 365 and 560ppm. Crops were simulated under both dryland and irrigated management, with irrigation water supply estimates taken from the HUMUS simulations in Paper 1. Texas, New Mexico, Colorado, Utah, Arizona, and California are projected to experience significant temperature increases by 2030. Slight cooling is expected by 2030 in Alabama, Florida, Maine, Montana, Idaho, and Utah. Larger areas are projected to experience increased warming by 2095. Uniform precipitation increases are expected by 2030 in the northeast. These increases are predicted to expand to the eastern half of the country by 2095. Regionally, dryland corn yields could increase, decrease or remain unchanged under the two scenarios. EPIC simulated yield increases for the Great Lakes, Corn Belt and Northeast regions. Simulated yields of irrigated corn were predicted to increase in almost all regions. Soybean yields could decrease in the Northern and Southern Plains, the Corn Belt, Delta, Appalachian, and Southeast regions and increase in the Lakes and Northeast regions. Simulated wheat yields exhibited upward trends under scenarios of climate-change. Evapotranspiration in dryland corn is expected to increase in both future periods while water-use efficiency will decrease. National corn production in 2030 and 2095 could be affected by changes in three major producing regions. In 2030, corn production could increase in the Corn Belt and Lakes regions but decrease in the Northern Plains leading to an overall decrease in national production. National wheat production is expected to increase during both future periods. A proxy indicator was developed to provide a sense of where in the country, and when water would be available to satisfy change in irrigation demand for corn and alfalfa production as these are influenced by the HadCM2 scenarios and CO2-fertilization. Irrigation requirement by irrigated crops declines under these scenarios as transpiration is suppressed.

Pump and centrifugal separator apparatus  

SciTech Connect (OSTI)

The invention relates to agitating means for preventing the accumulation of particulate matter at the contaminate outlet orifices in a pump and centrifugal separator apparatus. The pump separator apparatus includes a rotatable casing forming a chamber for centrifugally separating the oil, water and contaminant matter in an oil well production fluid. The clean oil is collected by a stationary pitot tube in the chamber, the clean water is drawn off at an outlet port near the outer periphery of the chamber, and the dirty water and contaminants are discharged through outlet orifices formed in the outer wall of the casing. The agitating means includes rotating jet ports for directing streams of pressurized fluid tangentially along the inner surface of the casing to agitate accumulations of separated solid contaminant matter thereby preventing the clogging of the outlet orifices.

Geothermal Heat Pump Benchmarking Report  

SciTech Connect (OSTI)

A benchmarking study was conducted on behalf of the Department of Energy to determine the critical factors in successful utility geothermal heat pump programs. A Successful program is one that has achieved significant market penetration. Successfully marketing geothermal heat pumps has presented some major challenges to the utility industry. However, select utilities have developed programs that generate significant GHP sales. This benchmarking study concludes that there are three factors critical to the success of utility GHP marking programs: (1) Top management marketing commitment; (2) An understanding of the fundamentals of marketing and business development; and (3) An aggressive competitive posture. To generate significant GHP sales, competitive market forces must by used. However, because utilities have functioned only in a regulated arena, these companies and their leaders are unschooled in competitive business practices. Therefore, a lack of experience coupled with an intrinsically non-competitive culture yields an industry environment that impedes the generation of significant GHP sales in many, but not all, utilities.

Increasing positive displacement charging pump reliability  

SciTech Connect (OSTI)

The use of positive displacement pumps in many PWRs is an integral part of providing reactivity control via the Chemical and Volume Control system. This usually requires the continuous operation of at least one pump, typically with a flow rate of 44 gpm {at} 2,310 psig (167 lpm {at} 160 bar). Some PWRs use multiple pumps, and vary the letdown, while others use variable speed pumps. Regardless, the charging pumps run continuously. With the amount of reciprocating mass, differential pressure, and friction, it is a battle to maintain the pumps in peak operating condition for long periods of time. This paper will show how Entergy Operations` Waterford 3 SES was able to increase the reliability of the positive displacement Charging Pumps. Many different solutions were evaluated, and several adopted. The results are undeniable, as availability has increased and O and M costs have been reduced by 90% over 6 years.

Submersible canned motor transfer pump  

DOE Patents [OSTI]

A transfer pump used in a waste tank for transferring high-level radioactive liquid waste from a waste tank and having a column assembly, a canned electric motor means, and an impeller assembly with an upper impeller and a lower impeller connected to a shaft of a rotor assembly. The column assembly locates a motor housing with the electric motor means adjacent to the impeller assembly which creates an hydraulic head, and which forces the liquid waste, into the motor housing to cool the electric motor means and to cool and/or lubricate the radial and thrust bearing assemblies. Hard-on-hard bearing surfaces of the bearing assemblies and a ring assembly between the upper impeller and electric motor means grind large particles in the liquid waste flow. Slots in the static bearing member of the radial bearing assemblies further grind down the solid waste particles so that only particles smaller than the clearances in the system can pass therethrough, thereby resisting damage to and the interruption of the operation of the transfer pump. The column assembly is modular so that sections can be easily assembled, disassembled and/or removed. A second embodiment employs a stator jacket which provides an alternate means for cooling the electric motor means and lubricating and/or cooling the bearing assemblies, and a third embodiment employs a variable level suction device which allows liquid waste to be drawn into the transfer pump from varying and discrete levels in the waste tank.

Charge-pump voltage converter  

DOE Patents [OSTI]

A charge-pump voltage converter for converting a low voltage provided by a low-voltage source to a higher voltage. Charge is inductively generated on a transfer rotor electrode during its transit past an inductor stator electrode and subsequently transferred by the rotating rotor to a collector stator electrode for storage or use. Repetition of the charge transfer process leads to a build-up of voltage on a charge-receiving device. Connection of multiple charge-pump voltage converters in series can generate higher voltages, and connection of multiple charge-pump voltage converters in parallel can generate higher currents. Microelectromechanical (MEMS) embodiments of this invention provide a small and compact high-voltage (several hundred V) voltage source starting with a few-V initial voltage source. The microscale size of many embodiments of this invention make it ideally suited for MEMS- and other micro-applications where integration of the voltage or charge source in a small package is highly desirable.

Empirical evidence for a recent slowdown in irrigation-induced cooling  

SciTech Connect (OSTI)

Understanding the influence of past land use changes on climate is needed to improve regional projections of future climate change and inform debates about the tradeoffs associated with land use decisions. The effects of rapid expansion of irrigated area in the 20th century has remained unclear relative to other land use changes, such as urbanization, that affected a similar total land area. Using spatial and temporal variations in temperature and irrigation extent observed in California, we show that irrigation expansion has had a large cooling effect on summertime average daily daytime temperatures (-0.15 to -0.25 C.decade{sup -1}), which corresponds to a cooling estimated at -2.0 - -3.3 C since the introduction of irrigation practice. Irrigation has negligible effects on nighttime temperatures, leading to a net cooling effect of irrigation on climate (-0.06 to -0.19 C.decade{sup -1}). Stabilization of irrigated area has occurred in California since 1980 and is expected in the near future for most irrigated regions. The suppression of past human-induced greenhouse warming by increased irrigation is therefore likely to slow in the future, and a potential decrease in irrigation may even contribute to a more rapid warming. Changes in irrigation alone are not expected to influence broadscale temperatures, but they may introduce large uncertainties in climate projections for irrigated agricultural regions, which provide roughly 40% of global food production.

Evaluation of supply potential of energy crops in Japan considering cases of improvement of crop productivity  

Science Journals Connector (OSTI)

Energy crops are not presently major energy resources as energy crops are more expensive than fossil fuels at present. However, energy crops may become important energy resources in the future. In this study, the authors discuss the availability of energy crops in Japan. The supply potential of energy crops produced on unused arable land is estimated at 0.12EJyr?1 and that of secondary crops for bioenergy is estimated at 0.12EJyr?1 in Japan. However, it is difficult to utilize the supply potential considering the low food-self-sufficiency ratio and the high costs of crops in Japan. In addition, the authors analyze the supply potential of energy crops produced on surplus arable land in Japan in cases of biomass productivity increment. The supply potential of energy crops is formulated into 0.12A (EJyr?1), where A means the index of productivity increment ( A = 1.0 at present). On the other hand, in the case of every crop productivity increment, the supply potential of energy crops is formulated into 1.44A1.32 (EJyr?1). When it is assumed that the ratio is 2.0, the supply potential in the latter case is 1.44EJyr?1, which is equivalent to about 7% of the total primary energy supply in Japan. When it is assumed that the ratio is 2.0 in the latter case in the world, the supply potential of energy crops is 435EJyr?1, which exceeds the total primary energy supply in the world. It is difficult to improve the productivity of every crop. However, if the improvement is realized, energy crops will become one of the major energy resources in Japan and in the world.

Heat Pump Basics Heat Pump Basics Photo of the West Philadelphia Enterprise Center. The West Philadelphia Enterprise Center uses a geothermal heat pump system for more than 31,000 square feet of space. Geothermal heat pumps take advantage of the nearly constant temperature of the Earth to heat and cool buildings. The shallow ground, or the upper 10 feet of the Earth, maintains a temperature between 50° and 60°F (10°-16°C). This temperature is warmer than the air above it in the winter and cooler in the summer. Geothermal heat pump systems consist of three parts: the ground heat exchanger, the heat pump unit, and the air delivery system (ductwork). The heat exchanger is a system of pipes called a loop, which is buried in the shallow ground near the building. A fluid (usually water or a mixture of

Heat Pump Basics Heat Pump Basics Geothermal Heat Pump Basics August 19, 2013 - 11:12am Addthis Text Version Geothermal heat pumps use the constant temperature of the earth as an exchange medium for heat. Although many parts of the country experience seasonal temperature extremes-from scorching heat in the summer to sub-zero cold in the winter-the ground a few feet below the earth's surface remains at a relatively constant temperature. Depending on the latitude, ground temperatures range from 45°F (7°C) to 75°F (21°C). So, like a cave's, the ground's temperature is warmer than the air above it during winter and cooler than the air above it in summer. Geothermal heat pumps take advantage of this by exchanging heat with the earth through a ground heat exchanger. Geothermal heat pumps are able to heat, cool, and, if so equipped, supply

How does it work? A geothermal heat pump uses the constant below ground temperature of soil or water to heat and cool your home. Geothermal heat pumps (GHPs), sometimes referred to as GeoExchange, earth-coupled, ground-source, or water-source heat pumps, have been in use since the late 1940s. They use the constant temperature of the earth as the exchange medium instead of the outside air temperature. This allows the system to reach fairly high efficiencies (300% to 600%) on the coldest

Biomass yield and nitrogen content of annual energy/forage crops preceded by cover crops  

Science Journals Connector (OSTI)

Abstract In order to reduce input costs and improve sustainability of energy/forage crops in the northern Great Plains (NGP), preceding cover crops can be included into existing annual crop systems. The objective of the study was to determine biomass yield and quality of five annual energy/forage crops, grown after six different, leguminous and non-leguminous cover crop species. The experiment was conducted at two locations, Fargo and Prosper, ND, from 2010 to 2012. The experimental design was a randomized complete block with three replicates, in a split-plot arrangement where the preceding season's cover crop was the main plot and the forage crop was the sub-plot. Six cover crops, forage pea (Pisum sativum L.) cv. Arvika, Austrian winter pea (Pisum sativum ssp. arvense (L.) Poir), hairy vetch (Vicia villosa Roth.) forage radish (Raphanus sativus var. niger) cv. Daikon, turnip (Brassica rapa var. rapa) cv. Purple Top, and forage turnip (Brassica campestris x napus) cv. Pasja, were planted no-till on 8 to 9 August in 2010 and 2011 into oat (Avena sativa L.) residue. In the following spring, five energy/forage crops, maize (Zea mays L.), forage sorghum and sweet sorghum (Sorghum bicolor L.), oat, and barley (Hordeum vulgare L.) were planted no-till onto the winter-killed cover crops residue. Results across locations and years indicated forage pea and forage radish, produced the highest dry matter yield (3.3Mgha?1) in the fall. Total plant N content was 116kgNha?1 in forage peas and 76kgNha?1 in forage radish, respectively. Results across locations and years indicated all energy/forage crops had greater biomass yield, and total N content when preceded by a legume cover crop compared with a non-legume or the check, in the previous year. Forage sorghum had the highest average biomass yield among the five energy/forage crops, with 17.8Mgha?1, followed by sweet sorghum with 15.3Mgha?1. In conclusion, forage pea was the most suitable cover crop to provide additional N for the subsequent crops in the NGP. Forage sorghum and sweet sorghum can be considered as the most productive energy/forage crops, especially when preceded by a legume cover crop.

Transport and Dissipation in Quantum Pumps  

E-Print Network [OSTI]

This paper is about adiabatic transport in quantum pumps. The notion of ``energy shift'', a self-adjoint operator dual to the Wigner time delay, plays a role in our approach: It determines the current, the dissipation, the noise and the entropy currents in quantum pumps. We discuss the geometric and topological content of adiabatic transport and show that the mechanism of Thouless and Niu for quantized transport via Chern numbers cannot be realized in quantum pumps where Chern numbers necessarily vanish.

Industrial heat pumps - types and costs  

SciTech Connect (OSTI)

Confusion about energy savings and economics is preventing many potentially beneficial applications for industrial heat pumps. The variety of heat pumps available and the lack of a standard rating system cause some of this confusion. The authors illustrate how a simple categorization based on coefficient of performance (COP) can compare the cost of recovering waste energy with heat pumps. After evaluating examples in which the cost of energy delivered was calculated based on estimates of capital cost, operating costs, and maintenance costs, they compare heat pumps from the various categories on the basis of economics. 6 references, 6 figures, 1 table.

Centrifugal pumps design and application. Second edition  

SciTech Connect (OSTI)

This book is a practical textbook stressing hydraulic design, that could be of hands-on use to the pump designer, student, and rotating equipment engineer. Although feedback from readers indicates that we achieved our desired goal, we did recognize that we had omitted several important topics. We had the little about the design of chemical pumps and touched only lightly on the extensive range of composite materials and the manufacturing techniques used in nonmetallic pump applications. We had totally ignored the subject of mechanical seals, yet we fully recognized that a knowledge of seal fundamentals and theory of operation is essential to the pump designer and rotating equipment engineer. Another major omission was the subject of vibration and noise in centrifugal pumps. With today's high energy pumps operating at ever increasing speeds, it is essential that we understand the sources of pump noise and causes of vibration that result from installation, application, cavitation, pulsation, or acoustic resonance. Although we had touched lightly on rotor dynamics, we felt this subject deserved to be expanded, particularly in the areas of bearing stiffness and damping, seal effects, and the evaluation of critical speed calculations. Finally, we had the nothing about the knowledge necessary to extend pump life during installation and operation, which requires a deep understanding of bearings, lubrication, mechanical seal reliability, and the external alignment of pump and driver.

We relate the charge in BPT to Berry's phase and the corresponding Brouwer pumping formula to curvature. As applications we derive explicit formulas for the joint probability density of pumping and conductance when the S matrix is uniformly distributed; and derive a new formula that describes hard pumping when the S matrix is periodic in the driving parameters.

Only solid waste particles smaller than the clearances in the system can pass there through, thereby resisting damage to and the interruption of the operation of the mixer pump. 10 figs.

Heat pump associations, alliances, and allies  

SciTech Connect (OSTI)

Associations, Alliances, and Allies, a seminar and workshop sponsored by the Electric Power Research Institute, was held in Memphis, Tennessee, April 10--11, 1991. The focus of the meeting was relationships forged between electric utilities and trade allies that sell residential heat pumps. one hundred and seven representatives of electric utilities, dealer/contractors, manufacturers, and consultants attended. Electric utility trade ally programs run the gamut from coop advertising to heat pump association to elaborate technician training programs. All utility participants recognize the important programs, since it is the trade ally who sells, installs, and services heat pumps, while it is the electric utility who gets blamed if the heat pumps fail to operate properly or are inefficient. Heat pumps are efficient and effective, but their efficiency and effectiveness depends critically upon the quality of installation and maintenance. A utility can thus help to ensure satisfied customers and can also help to achieve its own load shape objectives by working closely with its trade allies, the dealers, contractors, manufacturers, and distributors. Attendees spent the morning sessions of the two day meeting in plenary sessions, hearing about utility and dealer heat pump programs and issues. Afternoon roundtable discussions provided structured forums to discuss: Advertising; Heat pump association startup and operation; Rebates and incentives; Technician training school and centers; Installation inspection and dealer qualification; and Heat pump association training. These proceedings report on the papers presented in the morning plenary sessions and summarize the main points discussed in the afternoon workshops.

Land treatment of contaminated sludge with wastewater irrigation  

SciTech Connect (OSTI)

A large-scale field experiment was conducted to test the feasibility of land application of sludge from industrial and domestic wastewater treatment to determine the fate and environmental impact of the contaminants. The sludge contained 13 organic priority pollutants, 16 additional environmentally significant organic compounds, and high concentrations of several metals (zinc, copper, lead, nickel, and cadmium). Each compound was monitored as the irrigation water percolated through the soil and the groundwater over time. Most of the organic compounds diminished to non-detectable levels by the end of the study, and the metals proved harmless to the environment. The effectiveness of land application of sludge with wastewater irrigation was clearly demonstrated. 1 figure, 11 tables.

Nutrient removal by grasses irrigated with wastewater and nitrogen balance for reed canarygrass  

SciTech Connect (OSTI)

To develop complementary wastewater treatment systems that increase nutrient reduction and recycling, an experiment was conducted to evaluate the efficiency of three grass species as catch crops for N, P, and K at Aurahammar wastewater treatment plant (WWTP) in the southern part of Sweden. Another objective was also to assess soil accumulation of N, P, and K and the risk of N leaching by drainage. Three grasses--reed canarygrass (Phalaris arundinacea L.), meadow foxtail (Alopecurus pratensis L.), and smooth bromegrass (Bromus inermis Leyss.)--were irrigated with a mixture of treated effluent and supernatant at two levels of intensity [optimum level (equal to evapotranspiration) and over-optimal level] and at two nutrient levels, approximately 150 and 300 kg N ha{sup {minus}1}. There were small differences in dry matter (DM) yield between grass species and no difference in N removal among species. The amount of N removed in harvested biomass to N applied was 0.58 in 1995 and 0.63 in 1996. The amount of N removed increased with increased nutrient load. Applied amounts of P were the same as P in harvested biomass. All species removed K amounts several times greater than applied amounts. Increased nutrient load increased overall K removal. The low amount of mineral N and especially NO{sub 3}{sup {minus}}-N in the soil profile in autumn samplings indicate the risk for leaching is small. Soil water NO{sub 3}{sup {minus}} contents were also low, <2.5 mg NO{sub 3}{sup {minus}}-N L{sup {minus}1} during the growing season, with a mean value of <1 mg NO{sub 3}{sup {minus}}-N L{sup {minus}1}.

Growth and biomass of Populus irrigated with landfill leachate  

Science Journals Connector (OSTI)

Resource managers are challenged with waste disposal and leachate produced from its degradation. Poplar (Populus spp.) trees offer an opportunity for ecological leachate disposal as an irrigation source for managed tree systems. Our objective was to irrigate Populus trees with municipal solid waste landfill leachate or fertilized well water (control) (N, P, K) during the 2005 and 2006 growing seasons and test for differences in tree height, diameter, volume, and biomass of leaves, stems, branches, and roots. The trees were grown at the Oneida County Landfill located 6km west of Rhinelander, Wisconsin, USA (45.6N, 89.4W). Eight clones belonging to four genomic groups were tested: NC13460, NC14018 [(Populus trichocarpa Torr. & GrayנPopulus deltoides Bartr. ex Marsh)נP. deltoides BC1]; NC14104, NC14106, DM115 (P. deltoidesנPopulus maximowiczii A. Henry DM); DN5 (P. deltoidesנPopulus nigra L. DN); NM2, NM6 (P. nigraנP. maximowiczii NM). The survival rate for each of the irrigation treatments was 78%. The total aboveground biomass ranged from 0.51 to 2.50Mgha?1, with a mean of 1.57Mgha?1. The treatmentנclone interaction was not significant for tree diameter, total volume, dry mass of the stump or basal roots, or root mass fraction (P>0.05). However, the treatmentנclone interaction was significant for height, total tree dry mass, aboveground dry mass, belowground dry mass, and dry mass of the leaves, stems+branches (woody), and lateral roots (P<0.05). There was broad clonal variation within the BC1 and DM genomic groups, with genotypes performing differently for treatments. In contrast, the performance of the NM and DN genomic groups was relatively stable across treatments, with clonal response to irrigation being similar regardless of treatment. Nevertheless, selection at the clone level also was important. For example, NC14104 consistently performed better when irrigated with leachate compared with water, while NC14018 responded better to water than leachate. Overall, these data will serve as a basis for researchers and resource managers making decisions about future leachate remediation projects.

Raft river geothermal pump disassembly and inspection  

SciTech Connect (OSTI)

The disassembly and postoperation inspection of the Peerless geothermal water pump used in teh RRGE-1 well at the Raft River Geothermal Test Site are summarized. Disassembly was hampered by scale that froze some of the pump bearings onto the impeller shaft after operation ceased. The pump appeared otherwise in generally excellent condition after more than 1600 h running time in a geothermal environment. Most postoperation diameters of rotating parts were still within factory tolerance. The few out-of-tolerance bearing diameters could not be attributed to wear and could have been out of tolerance when received. This possibility points to a need for preoperation quality-control inspection of the bearings.

Canned pump having a high inertia flywheel  

DOE Patents [OSTI]

A canned pump is described which includes a motor, impeller, shaft, and high inertia flywheel mounted within a hermetically sealed casing. The flywheel comprises a heavy metal disk made preferably of a uranium alloy with a stainless steel shell sealably enclosing the heavy metal. The outside surfaces of the stainless steel comprise thrust runners and a journal for mating with, respectively, thrust bearing shoes and radial bearing segments. The bearings prevent vibration of the pump and, simultaneously, minimize power losses normally associated with the flywheel resulting from frictionally pumping surrounding fluid. 5 figs.

DOE Patents [OSTI]

A method and apparatus is provided for producing near-diffraction-limited laser light, or amplifying near-diffraction-limited light, in diode pumped alkali vapor photonic-band-gap fiber lasers or amplifiers. Laser light is both substantially generated and propagated in an alkali gas instead of a solid, allowing the nonlinear and damage limitations of conventional solid core fibers to be circumvented. Alkali vapor is introduced into the center hole of a photonic-band-gap fiber, which can then be pumped with light from a pump laser and operated as an oscillator with a seed beam, or can be configured as an amplifier.

DOE Patents [OSTI]

A solid state radiative heat pump operable at room temperature (300 K) utilizes a semiconductor having a gap energy in the range of 0.03-0.25 eV and operated reversibly to produce an excess or deficit of change carriers as compared equilibrium. In one form of the invention an infrared semiconductor photodiode is used, with forward or reverse bias, to emit an excess or deficit of infrared radiation. In another form of the invention, a homogenous semiconductor is subjected to orthogonal magnetic and electric fields to emit an excess or deficit of infrared radiation. Three methods of enhancing transmission of radiation the active surface of the semiconductor are disclosed. In one method, an anti-refection layer is coated into the active surface of the semiconductor, the anti-reflection layer having an index of refraction equal to the square root of that of the semiconductor. In the second method, a passive layer is speaced trom the active surface of the semiconductor by a submicron vacuum gap, the passive layer having an index of refractive equal to that of the semiconductor. In the third method, a coupler with a paraboloid reflecting surface surface is in contact with the active surface of the semiconductor, the coupler having an index of refraction about the same as that of the semiconductor.

Industrial heat pumps: types and costs  

SciTech Connect (OSTI)

Many potentially beneficial applications for industrial heat pumps are not being pursued because of confusion regarding both energy savings and economics. Part of this confusion stems from the variety of heat pumps available and the fact that the measure of merit, the coefficient of performance (COP), is commonly defined in at least three different ways. In an attempt to circumvent this problem, a simple categorization was developed based on the commonly accepted COP definitions. Using this categorization, the cost of recovering waste energy with heat pumps was examined. Examples were evaluated in which the cost of energy delivered was calculated based on estimates of capital cost, operating costs, and maintenance costs. Heat pumps from the various categories were then compared on the basis of economics.

Chemical heat pump project: Final report  

SciTech Connect (OSTI)

Solid/vapor working media can be used as working fluids in industrial heat pumps for heat amplifier and temperature amplifier concepts. This report describes the theoretical investigation of candidate solid/vapor fluids and the development of single and multi-stage heat pump cycles. Ammoniated complex compounds, hydrated complex compounds, metal carbonate-metal oxide media, and metal hydrides were investigated. A preliminary computer model was developed to predict the performance characteristics of a single-stage complex compound temperature amplifier and to outline the limitations of such concepts. A preliminary first cost calculation was performed in order to determine the economical feasibility of solid/vapor industrial heat pumps in comparison to boilers nd state-of-the-art heat pump equipment.

Apply reliability centered maintenance to sealless pumps  

SciTech Connect (OSTI)

This paper reports on reliability centered maintenance (RCM) which is considered a crucial part of future reliability engineering. RCM determines the maintenance requirements of plants and equipment in their operating context. The RCM method has been applied to the management of critical sealless pumps in fire/toxic risk services, typical of the petrochemical industry. The method provides advantages from a detailed study of any critical engineering system. RCM is a team exercise and fosters team spirit in the plant environment. The maintenance strategy that evolves is based on team decisions and relies on maximizing the inherent reliability built into the equipment. RCM recommends design upgrades where this inherent reliability is being questioned. Sealless pumps of canned motor design are used as main reactor charge pumps in PVC plants. These pumps handle fresh vinyl chloride monomer (VCM), which is both carcinogenic and flammable.

Anomalous Topological Pumps and Fractional Josephson Effects  

E-Print Network [OSTI]

We discover novel topological pumps in the Josephson effects for superconductors. The phase difference, which is odd under the chiral symmetry defined by the product of time-reversal and particle-hole symmetries, acts as an anomalous adiabatic parameter. These pumping cycles are different from those in the "periodic table", and are characterized by $Z\\times Z$ or $Z_2\\times Z_2$ strong invariants. We determine the general classifications in class AIII, and those in class DIII with a single anomalous parameter. For the $Z_2\\times Z_2$ topological pump in class DIII, one $Z_2$ invariant describes the coincidence of fermion parity and spin pumps whereas the other one reflects the non-Abelian statistics of Majorana Kramers pairs, leading to three distinct fractional Josephson effects.

Optical pumping into many-body entanglement  

E-Print Network [OSTI]

We propose a scheme of optical pumping by which a system of atoms coupled to harmonic oscillators is driven to an entangled steady state through the atomic spontaneous emission. It is shown that the optical pumping can be tailored so that the many-body atomic state asymptotically reaches an arbitrary stabilizer state regardless of the initial state. The proposed scheme can be suited to various physical systems. In particular, the ion-trap realization is well within current technology.

It imposes strong restrictions on the currents generated by periodic driving in a generic dissipative system with detailed balance. Our theorem unifies previously known results with the new ones and provides a universal nonperturbative approach to explore further restrictions on the stochastic pump effect in non-adiabatically driven systems.

Vertical pump turbine oil environmental evaluation  

SciTech Connect (OSTI)

In Oregon low-temperature geothermal injection well construction, siting and receiving formations requires approval by the Water Resources Department (OWRD). In addition, the Oregon Department of Environmental Quality (ODEQ) has regulations concerning injection. Conversations with the OWRD and ODEQ representatives indicated they were very concerned about the potential for contamination of the geothermal (and cooler but hydraulically connected) aquifers by oils and grease. Their primary concern was over the practice of putting paraffin, motor oils and other hydrocarbons in downhole heat exchanger (DHE) wells to prevent corrosion. They also expressed considerable concern about the use of oil in production well pumps since the fluids pumped would be injected. Oregon (and Idaho) prohibit the use of oil-lubricated pumps for public water supplies except in certain situations where non-toxic food-grade lubricants are used. Since enclosed-lineshaft oil-lubricated pumps are the mainstay of direct-use pumping equipment, the potential for restricting their use became a concern to the Geo-Heat Center staff. An investigation into alternative pump lubrication schemes and development of rebuttals to potential restrictions was proposed and approved as a contract task. (SM)

Pumping station design for a pumped-storage wind-hydro power plant  

Science Journals Connector (OSTI)

This work presents a numerical study of the optimum sizing and design of a pumping station unit in a hybrid wind-hydro plant. The standard design that consists of a number of identical pumps operating in parallel is examined in comparison with two other configurations, using one variable-speed pump or an additional set of smaller jockey pumps. The aim is to reduce the amount of the wind generated energy that cannot be transformed to hydraulic energy due to power operation limits of the pumps and the resulting step-wise operation of the pumping station. The plant operation for a period of one year is simulated by a comprehensive evaluation algorithm, which also performs a detailed economic analysis of the plant using dynamic evaluation methods. A preliminary study of the entire plant sizing is carried out at first using an optimization tool based on evolutionary algorithms. The performance of the three examined pumping station units is then computed and analyzed in a comparative study. The results reveal that the use of a variable-speed pump constitutes the most effective and profitable solution, and its superiority is more pronounced for less dispersed wind power potential.

Selection of fluids for tritium pumping systems  

SciTech Connect (OSTI)

The degradation characteristics of three types of vacuum pump fluids, polyphenyl ethers, perfluoropolyethers and hydrocarbon oils were reviewed. Fluid selection proved to be a critical factor in the long-term performance of tritium pumping systems and subsequent tritium recovery operations. Thermal degradation and tritium radiolysis of pump fluids produce contaminants which can damage equipment and interfere with tritium recovery operations. General characteristics of these fluids are as follows: polyphenyl ether has outstanding radiation resistance, is very stable under normal diffusion pump conditions, but breaks down in the presence of oxygen at anticipated operating temperatures. Perfluoropolyether fluids are very stable and do not react chemically with most gases. Thermal and mechanical degradation products are inert, but the radiolysis products are very corrosive. Most of the degradation products of hydrogen oils are volatile and the principal radiolysis product is methane. Our studies show that polyphenyl ethers and hydrocarbon oils are the preferred fluids for use in tritium pumping systems. No corrosive materials are formed and most of the degradation products can be removed with suitable filter systems.

Cold Climates Heat Pump Design Optimization  

SciTech Connect (OSTI)

Heat pumps provide an efficient heating method; however they suffer from sever capacity and performance degradation at low ambient conditions. This has deterred market penetration in cold climates. There is a continuing effort to find an efficient air source cold climate heat pump that maintains acceptable capacity and performance at low ambient conditions. Systematic optimization techniques provide a reliable approach for the design of such systems. This paper presents a step-by-step approach for the design optimization of cold climate heat pumps. We first start by describing the optimization problem: objective function, constraints, and design space. Then we illustrate how to perform this design optimization using an open source publically available optimization toolbox. The response of the heat pump design was evaluated using a validated component based vapor compression model. This model was treated as a black box model within the optimization framework. Optimum designs for different system configurations are presented. These optimum results were further analyzed to understand the performance tradeoff and selection criteria. The paper ends with a discussion on the use of systematic optimization for the cold climate heat pump design.

High-speed pumping to UHV  

Science Journals Connector (OSTI)

Development of a high-speed pumping system for ultra high vacuum (UHV) process dose not reduce only cost and waiting time for experiment and production, but also reduces CO2 emission that is known as one of the serious causes in the global warming problem. Reduction of vapor water concentration in a purge gas line would be one of the most effective measures to reduce pumping time to UHV. We carried out control of water vapor in a nitrogen gas purge line in addition to surface treatments of chambers using buff polishing and electrolytic polishing, followed by measurement of outgassing rate of the chambers. Under the reasonable control of the water vapor, the pumping time to reach the pressure of 1נ10?6Pa was able to be shortened with two orders of the magnitude. And it was also found that the main residual gas in the chamber was hydrogen after pumping down with the low concentration of water vapor. The quality of residual gas was equivalent to the quality in a baked UHV system. The introduction of well controlled nitrogen gas to the vacuum system which was not baked out during its pumping has proved a pressure of 3נ10?8Pa for 24h in the chamber without orifice.

Tank 26 Evaporator Feed Pump Transfer Analysis  

SciTech Connect (OSTI)

The transfer of liquid salt solution from Tank 26 to an evaporator is to be accomplished by activating the evaporator feed pump, located approximately 72 inches above the sludge layer, while simultaneously turning on the downcomer. Previously, activation of the evaporator feed pump was an isolated event without any other components running at the same time. An analysis of the dissolved solution transfer has been performed using computational fluid dynamics methods to determine the amount of entrained sludge solids pumped out of the tank to the evaporator with the downcomer turned on. The analysis results showed that, for the maximum and minimum supernate levels in Tank 26 (252.5 and 72 inches above the sludge layer, respectively), the evaporator feed pump will entrain between 0.03 and 0.1 wt% sludge undissolved solids weight fraction into the eductor, respectively, and therefore are an order of magnitude less than the 1.0 wt% undissolved solids loading criteria to feed the evaporator. Lower tank liquid levels, with respect to the sludge layer, result in higher amounts of sludge entrainment due to the increased velocity of the plunging jets from the downcomer and evaporator feed pump bypass as well as decreased dissipation depth. Revision 1 clarifies the analysis presented in Revision 0 and corrects a mathematical error in the calculations for Table 4.1 in Revision 0. However, the conclusions and recommendations of the analysis do not change for Revision 1.
