摘要：

In this paper, the heat transfer and pressure drop performance of several different geometric models are investigated numerically in low-corrugated channels. The variation of heat transfer coefficient and pressure drop with velocity are obtained in a certain range of flow rate. Effects of the channel height, wave height and channel width on the flow and heat transfer are analyzed. The results show that the heat transfer and pressure drop both decrease with the increase of the channel height; With the increase of the wave height, heat transfer is enhanced and the pressure drop increases simultaneously, with the increase of the channel width, the pressure drop decreases while the heat transfer is almost the same.
