Extensive tabular results for the exchanger temperature effectiveness and the log-mean temperature difference correction factor are presented for a wide range of the number of transfer units, heat capacity rate ratio and the number of thermal plates. The "end effect" due to a small number of thermal plates is important only for N < 40. In most plate exchangers the number of thermal plates is greater than 40. For this case, the influence of the number of thermal plates is found to be negligible on the performance, i.e., the performance approaches that of an eXChanger with an infinite number of thermal plates. Based on the results, design guidelines are also presented for the select ion ofa 1-1, 2-1 or 3-1 pass exchanger when the heat capacity rate ratio is about two and higher.
