Summary

A finite element analysis of a crossflow tube-fin compact heat exchanger is presented (water in tube, air outside). The analysis takes into account the combined effects of one-dimensional longitudinal heat conduction through the exchanger wall and nonuniform inlet fluid flow and temperature distributions on both hot and cold fluid sides. A mathematical equation is developed to generate different types of fluid flow/temperature maldistribution models. Using these models, the exchanger effectiveness and its deterioration due to the combined effects of longitudinal heat conduction and flow/temperature nonuniformity are calculated for various design and operating conditions of the exchanger.
