摘要：
In this study, heat transfer and pressure drop characteristics of air flow in corrugated channels have been experimentally investigated. Experiments were performed on channels of uniform wall heat flux and varied Reynolds Number (Re) from 2000 to 9000. Four different types, two sharp and two rounded corrugation peak, finned plates are used in present experiments. The effects of channel height on heat transfer and pressure drop are obtained and discussed. The increase of corrugated angle and channel height tends to increase heat transfer.
