A numerical method to determine the effectiveness of the crossflow heat exchanger, accounting for the effect of the two-dimensional longitudinal heat conduction through the exchanger wall structure in the directions of fluid flows, is presented. The exchanger effectiveness and its deterioration due to the conduction effect have been calculated for various design and operating conditions of the exchanger. The results indicate that the thermal performance deterioration of the exchanger may become significant for some typical applications.
