Solar Energy Storage in Packed Beds

Abstract

A theoretical model is developed to describe the dynamic performance of solar energy storage in packed beds for grain drying. Results are obtained in response to a clear-day solar insolation. The model determines the dynamics of the collector, dryer, and energy storage device. The effects of various system parameters on the response of air temperatures in the three units are determined. The method is general and can also be applied to the drying of any kinds of granular hygroscopic materials, biological as well as non-biological.
