A numerical study is performed to investigate unsteady, two-dimensional, incompressible laminar flow over both sides of a slot-perforated flat surface in a pulsating channel flow. Consideration is given to the effects of the pulsating Strouhal number , the Reynolds number Re, and the blockage factor, i.e., the ratio of plate thickness, , to channel width, , on the heat-transfer performance and the velocity and thermal fields. It is found from the study that (i) time-averaged Nusselt number at the rear plate is amplified with Re, (ii) in contrast, the corresponding performance is attenuated with an increase in the blockage factor, whose effect becomes larger in the lower region of the Reynolds number, i.e., , and (iii) enhancement of the Nusselt number causes an increase in , whose effect becomes minor near in the region of .
