An analytical and experimental investigation is being performed of heat and mass extraction from a solar pond by recirculating hot brine from the storage layer through an external heat exchanger. This process consists of continuous of intermittent recirculation of fluid from an initially convective layer. This layer is bounded above by a stratified region (gradient), although there is no physical partition separating these two regions, and it is bounded below by a horizontal plane (bottom of the pond) which is periodically heated by the sunlight penetrating to this depth and absorbed on the plane. Additionally, intermittent volumetric heating occurs in the bulk of the pond as a result of radiation absorption. Accomplishments in the first year of this effort include: reviewing the literature on the subject of heat and mass extraction from the storage layer of salt-gradient solar pond and related topics; defining possible extraction processes; identifying the parameters which limit the extraction rate on the basis of gradient stability; presenting a simple analytical model of the extraction processes; designing a suitable laboratory test facility; and defining specific measurements to be performed and accuracy requirements.
