The present study investigates the transient temperature behavior of a direct transfer type, single-pass, crossflow heat exchanger with neither gas mixed, accounting for the two-dimensional longitudinal conduction effect on the separator sheet. Numerical results show the variation of the mean exit temperatures of hot and cold gases. The approaching time to steady state is also presented to describe the influence of longitudinal conduction and number of transfer units. Finally, comparisons among step, ramp, and exponential responses are demonstrated to display thermal performance deterioration due to the wall conduction effect.
