The Phase Change Energy Storage System constitutes a key element of the Solar Dynamic Power System now being considered for the Space Station. The stored energy is provided to the Energy Conversion System during the non-illuminated portion of the orbit. This cyclic nature of the application requires understanding of the transient behavior of the Energy Storage System. A one dimensional thermal model was developed that uses a fixed-grid, implicit finite-difference formulation to handle the transient interface condition between the liquid and solid phases. This model was applied to a conceptual design of solar thermal receiver based on radiative coupling between the thermal energy storage container and the heat exchanger for the working fluid. Transient results indicate that the proposed design concept can meet the Space Station requirements.
