Abstract
The effectiveness of a plate heat exchanger with a finite number of plates is affected by the end channels, and the channels between two adjacent passes. These effects become less significant as the number of thermal plates becomes large, N > 40, as shown by Kandlikar and Shah (1989). In the present paper, closed-form equations are derived for plate heat exchangers with N = infinity in terms of temperature effectiveness Psub 1 as a function of the capacity rate ratio Rsub 1 and the number of transfer units NTUsub 1 for the following pass arrangements: 1-1, 2-1, 2-2, 3-1, 3-2, 3-3, 4-1, 4-2, 4-3, and 4-4.
