Краткое описание

A theoretical study is performed to investigate unsteady, two-dimensional, incompressible laminar flow over both sides of a slot-perforated flat surface, which is placed in a channel. The effects of the blockage factor, i.e., the ratio of plate thickness, d, to channel width, W, and d/d, i.e., the ratio of slot width d to d, on the heat transfer performance and the velocity and thermal fields are disclosed. It is found that: (i) when the slot width is increased, the alternating change in the fluid flow disturbs the thermal boundary layer formed along the plate and induces mixing of the upper and lower streams of the plate downstream from the slot, resulting in amplification of heat-transfer performance; (ii) heat-transfer performance at the rear plate is induced with an increase in d/d and Re, and (iii) by contrast, heat-transfer performance is attenuated with an increase in the blockage factor whose effect becomes larger in the lower region of the Reynolds number.
