Investigation of Porous-Medium Solar-Pond Feasibility. Final Report

摘要

A feasibility study of a porous medium solar pond has been completed. In general, the results shown that a partially transparent bed of glass and water will not perform well as a solar pond non-convecting zone. Effective thermal conductivities for the glass/water bed are high, indicating significant convective motion. In addition, radiation transmission through several glass/water interfaces is low. Useful radiation transmission models for partially transparent porous mediums have been formulated and are presented. Finally, a numerical simulation of a porous medium in a solar pond storage zone has shown that significant performance increases can be obtained. (ERA citation 08:050969)
