Abstract
Heat storaging is an urgent demand for the saving of heat energy. This paper dealt with the storage of energy in a solid sensible heat storage unit of packed pebble bed type. In this storage unit, heat transfer gas exchanges the heat with pebbles during passing through the narrow zigzag channels in the packed bed. Since the amount of storaged thermal energy is time dependent, it is necessary to know the transient response characteristics of the heat storage unit. Dynamical heat transfer problems in the pebble bed were analized and the results of calculation were compared with the experimental ones which were obtained with a small scale alumina spheres- air heat storaging system. The agreement was fairly good.
