THE CALCULATION OF THE EFFICIENCY OF HEAT REGENERATORS
( Imperial College London )
The calculation of the efficiency (or thermal ratio) of a heat regenerator requires essentially the solution of a pair of simultaneous first-order partial differential equations in order to determine the temperatures of the fluid and of the matrix throughout one cycle of operation. A method is proposed in this paper which is partly iterative; its effectiveness is illustrated by three typical numerical results and, in particular, the question of convergence is discussed.
