Developing and upgrading of solar-system thermal-energy-storage simulation models. Final report
The project objectives were to: collect, standardize, and link existing thermal energy storage (TES) models from the literature and other contractors; correlate TES models with available TES component data; develop streamlined versions of validated TES component models; provide DOE and industry with a competent solar TES simulation tool. Rock bed and water tank models were collected and upgraded models developed. These models are superior and more detailed than other models presently available. Upgraded rock bed and water tank models were validated utilizing test data acquired for validation purposes. Validation results were excellent. Streamlined models which are superior in the use of computer time were explored and described. Rock bed and water tank detailed and streamlined models were incorporated into the TRNSYS library which is available on computer tape. Descriptions are included of the rock bed and water tank models including the assumptions that were made in the development of these models. The results of simulations and test results are compared which includes an axial temperature profile comparison during the operation of the thermal energy storage device. System simulations using the rock bed and water tank components in TRNSYS are shown with user manual additions required so that researchers may use these components for exploring individual problems. In addition, the code listing for each storage device is presented so that a detailed understanding of the code is possible.
