The effect of gas heat storage upon the performance of the thermal regenerator

Abstract Most mathematical models of a thermal regenerator incorporate the assumption that the residual gas in the regenerator packing is ejected at the end of a period of operation and the regenerator is refilled with new gas before the next period begins. It is further assumed that this idealised evacuating and refilling of the channels of the packing at each reversal causes no change in the packing temperature. This paper describes a model of the regenerator in which a representation of gas carryover is attempted. The effect of the carryover predicted by this model is presented.
