EXACT EXPLICIT EQUATIONS FOR SOME TWO- AND THREE-PASS CROSS FLOW HEAT EXCHANGER EFFECTIVENESS

ABSTRACT
A review of the effectiveness (ε ) - number of transfer units (NTU) - capacity rate ratio (ω) relationships for eight possible identical flow arrangements of two- and three-pass cross flow heat exchangers is presented. The flow arrangements are those with weaker fluid unmixed throughout and other stream mixed between the passes and unmixed in each pass, viz. the arrangements from [1] with flow patterns of fluid being interchanged. The results of the exact closed form solutions to the mean mixed temperatures between the passes are given for each configuration as well.
