Title: DETAILED LOOP MODEL (DLM) ANALYSIS OF LIQUID SOLAR THERMOSIPHONS WITH HEAT EXCHANGERS

Abstract

An analytical Detailed Loop Model (DLM) has been developed to analyze the performance of solar thermosiphon water heaters with heat exchangers in storage tanks. The model has been used to study the performance of thermosiphons as a function of heat exchanger characteristics, heat transfer fluids, flow resistances, tank stratification, and tank elevation relative to the collector. The results indicate that good performance can be attained with these systems compared to thermosiphons without heat exchangers.

  • This paper describes the analysis and design of the five kinds of heat exchangers used in the thermal storage subsystem of the 10 MWe Solar Central Receiver Pilot Plant, now becoming more known as ''Solar One''. The paper discusses the practices and standards used in the designs of the heat exchangers, lists the heat exchanger design requirements, and discusses the process conditions. The design assumptions and constraints, the geometrical considerations, and the tradeoff studies that were conducted to optimize the designs are also discussed. A description of each heat exchanger reveals the final design solution. Novel and unique features ofmore » a power plant that must operate on a daily sun-cycle are identified.« less

  • A two-phase closed thermosiphon made of a corrugated tube was developed to extend the application field of heat pipes. In the first paper, the thermal performance of the evaporator section was examined with the thermosiphons set vertical or tilted. The paper describes the thermal performance of the condenser section. A condensation heat-transfer coefficient is proposed as a function of Nusselt's theory modified by three parameters: the Lockhart--Martinelli parameter to consider the effect of vapor flow on the condensing surface, and two new parameters concerned with the effects of the inclination angle of the thermosiphon and the fill charge ratio ofmore » the working fluid. The former parameter has a linear relation with the condensation heat-transfer coefficient, and the latter two have a quadratic relation.« less
  • An experimental study was performed to investigate the effect of subcooling on the flow and heat transfer in two-phase double-tube thermosiphons with three types of inner tubes using water, ethanol, and Freon 113 as the working fluids. The same experiment for a single-tube thermosiphon was also carried out for comparison. As a result, a correlating expression for the heat-transfer coefficients in two-phase double- and single-tube thermosiphons is presented. The expression presented, by taking account of subcooling and the properties of working fluids, agreed well with the experimental data. The critical heat flux increased slightly with an increase in the degreemore » of subcooling, and the rate of increase for double-tube thermosiphon was bigger than that for the single-tube one. The circulation mass velocity first increased and then decreased, as the heat flux increased. After that, it increased again at a certain heat flux. This behavior was observe for both saturated and subcooled boiling. However, this curve was shifted to the larger heat-flux direction as the degree of sub-cooling increased.« less
  • This paper reports on an experimental study on heat-transfer coefficients and the critical heat flux in two-phase double-tube thermosiphons which was carried out, using water, ethanol and Freon 113 (R-113) as the working liquids. The same experiment for a single-tube thermosiphon was also performed for comparison. The effects of the top-end shape of the inner tubes on the heat-transfer coefficients and the critical heat flux were investigated in detail. As a result, it was shown that the heat-transfer coefficient was not significantly affected by the difference of the top-end shape, but the critical heat flux was very sensitive to themore » top-end shape of the inner tubes. For R-113, the critical heat flux in the thermosiphon with the inner tube or T- or disk-shape top-end, was more than four times as large as that in the single-tube thermosiphon.« less
