Abstract
Abstract
A distributed nonlinear mathematical model for investigation of regenerative heat exchangers of both rotating-matrix and fixed-matrix is described. A noniterative numerical integration scheme for a conjugate unsteady heat exchange problem of one-dimensional flow and two-dimensional wall conduction is developed. An example study of a regenerative heat exchanger with a rotary ceramic matrix is presented. The range of optimum rotation rates supplying the highest calorific efficiency to the regenerator is determined.
