摘要
The purpose of the present study is to assess the fl ow and heat transfer performance of a corrugation channel considering various corrugation heights. Furthermore, heat transfer enhancement mechanism is revealed. The results show that the Nusselt number off ered by a corrugation channel with H = 3, 4.5, and 6 mm is equal to around 41.89 to 123.07, 55.56 to 150.02, and 72.18 to 175. The Nusselt number with H = 6 mm is 42−72% higher than that with H = 3 mm. The results show that two peak values exist near the entrance and exit along the concave wall. Thus, a peak value and the lowest point appear near the entrance and the exit along the convex wall. Fluid recirculation zones are generated upstream of the concave wall and downstream of the convex wall. The thermal boundary layer becomes thinnest downstream of the corrugation for the concave wall and near the entrance of the corrugation for the convex wall. Moreover, the highest level of TKE concentrates on the convex wall.
