Abstract

The heat transfer between fluid streams in a matrix heat exchanger is controlled by different resistances namely conduction resistance in perforated plates, convective resistance, axial conduction through the wall and the matrix in the exchanger. In this paper closed-form expressions are presented for the effectiveness of matrix heat exchangers in terms of these different resistances. These expressions can be used to determine the effectiveness of a matrix heat exchanger of any shape (circular, rectangular etc.). Based on these expressions, a procedure is developed for the optimum sizing of balanced flow matrix heat exchangers. The procedure is illustrated with a numerical example.
