Title: HEAP: heat energy analysis program. A computer model simulating solar receivers

Abstract

Thermal design of solar receivers is commonly accomplished via approximate models, where the receiver is treated as an isothermal box with lumped quantities of heat losses to the surroundings by radiation, conduction and convection. These approximate models, though adequate for preliminary design purposes, are not detailed enough to distinguish between different receiver designs, or to predict transient performance under variable solar flux, ambient temperatures, etc. A computer code has been written for this purpose and is given the name HEAP, an acronym for Heat Energy Analysis Program. HEAP has a basic structure that fits a general heat transfer problem, but with specific features that are custom-made for solar receivers. The code is written in MBASIC computer language. This document explains the detailed methodology followed in solving the heat transfer problem, and includes a program flow chart, an explanation of input and output tables, and an example of the simulation of a cavity-type solar receiver.

  • RADSOLVER is a computer program which calculates the radiation energy transport in cavity type receivers having an arbitrary number of apertures through which collimated beams of solar radiation enter. In contrast to the common assumption of gray (or semi-gray) surfaces used in the modeling of radiation transport, RADSOLVER accounts for the wavelength-dependence of emission, absorption and reflection with a band model of the radiative properties. It is intended that this report serve both as an instruction manual for the use of the RADSOLVER code and a vehicle for presenting the underlying theory. Illustrative examples along with input and output aremore » presented.« less

    The engineering manual provides a complete companion documentation about the structure of the main program and subroutines, the preparation of input data, the interpretation of output results, access and use of the program, and the detailed description of all the analytic, logical expressions and flow charts used in computations and program structure. A numerical example is provided and solved completely to show the sequence of computations followed. The program is carefully structured to reduce both user's time and costs without sacrificing accuracy. The user would expect a cost of CPU time of approximately $5.00 per building zone excluding printing costs.more » The accuracy, on the other hand, measured by deviation of simulated consumption from watt-hour meter readings, was found by many simulation tests not to exceed + or - 10 percent margin.« less

    The problem of mixed convection from external receivers is considered. The governing partial differential equations are stated, and the numerical solution is obtained using Keller's box method. The computer code developed to predict the heat losses in the attached flow region is described. Special attention is given to treatment of some numerical difficulties that arise. Preliminary computational results for laminar three-dimensional mixed convection are presented and discussed. Future project efforts and planned extensions of the present code are described. (LEW)

    The energy flux distribution at the aperture of cavity receivers is an important parameter that characterizes the performance of point-focusing solar concentrators. Together with simplifying assumptions about cavity absorptance, emittance, and convective losses, good estimates of the dish-receiver collection efficiency as a function of incident flux and effective cavity temperature can be obtained. For detailed design of cavity receivers, however, it is necessary to determine the incident flux distribution on the interior surfaces. This information is needed ultimately to determine the resulting energy fluxes to the working fluid, temperature distributions within the cavity, and receiver performance. Knowing the incident fluxmore » distributions provides the designer with insights such as where hot-spots are likely to occur, where heat exchange surfaces are needed, and where more detailed analysis might be warranted. Solar receivers are heat exchangers and incident flux distributions are a fundamental aspect of their design. The objective of this effort was to develop a design tool with which the effects of concentrator and receiver geometry on energy distributions could be investigated. The principal interest was in obtaining the overall flux distributions within arbitrarily shaped cavities. CAV was selected as a starting point for this development because of its availability and because it interfaces with a thermal analysis program called CVT. It also has the advantage that it can accommodate a number of internal surface orientations and has been shown to agree very well with more sophisticated computer programs.« less

  • This document describes the computer program used in conceptual studies of phase change and sensible heat thermal energy storage systems. The model assumes the phase change media is contained in a tube-in-bath configuration. The sensible heat medium is contained in high pressure tanks. The program has been used in conjunction with, but is not necessarily limited to, a high temperature, gas-cooled solar power plant. The program represents a computer implementation of the engineering equations used to estimate the size and cost of a given thermal storage system design concept. A description of the model including a description of the inputsmore » and outputs of the program is presented.« less
