摘要：

in the present study, the numerical analysis on the heat transfer and flow developments in the channel with one-side corrugated plate under constant heat flux conditions is presented. The corrugated plate with the corrugated tile angles of 40 degrees is simulated with the channel height of 7.5 mm. The flow and heat transfer developments are simulated by the k-epsilon standard turbulent model. A finite volume method with the structured uniform grid system is employed for solving the model. Effects of relevant parameters on the heat transfer and flow developments are considered. Breaking and destabilizing in the thermal boundary layer are promoted as fluid flowing through the corrugated surface. Therefore, the corrugated surface has a significant effect on the enhancement of heat transfer. (C) 2008 Elsevier Ltd. All rights reserved.
