Title: Asymptotic effectlveness-NTU formulas for multipass plate heat exchangers
Author: Kandlikar, Satish; Shah, R.
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 = 00 in terms of temperature effectiveness PI as a function of the capacity rate ratio RI and the number of transfer units NTUI for the following pass arrangements: 1-1, 2-1, 2...2, 3-1, 3-2, 3-3, 41, 4-2, 4-3, and 4-4.
