The present study experimentally investigated the thermal response of heat storage made of porous silicon carbide, for comparison with dense alumina, in a simple system in which three heat storage were vertically aligned in a square duct. Those heat storages were heated with high-temperature air (900℃) and then cooled with room-temperature air. The temperature histories of “upstream and downstream air” and “the center and surface of each heat storages” were measured by a K-type thermocouple. As a result, porous silicon carbide heat storage bodies at all position showed low Biot number and higher thermal response than dense alumina heat storage.
