Abstract

The thermal performance of a moist air cross flow compact heat exchanger with two fluids unmixed is studied analytically and experimentally. The heat exchanger is modeled in two dimensions with heat and mass transfer taking place simultaneously. The mass transfer within the heat exchanger is analyzed using the analogy with convective heat transfer. A set of partial differential equations under steady state have been established on the basis of energy and mass balances. Using finite difference theory, the partial differential equations have been approximated as difference equations. Numerical solutions of the equations have been obtained to determine the temperature difference parameter, which reflects the thermal performance of the heat exchanger.
