- Abstract
- The storage of thermal energy at a suitable temperature level from sources such as solar energy or waste heat processes can make that energy available for space heating at a later time period. This report is concerned with sensible heat transfer that takes place in a thermal storage device composed of a porous material with a fluid (water) transpiring through it. Experiments were performed on a prototype thermal storage device and the results were compared to numerical values computed from an analytical model.
