Abstract��

Numerical simulation was performed to obtain heat transfer and flow resistance characteristics in a channel with zigzag divider wall. Six configurations with different diameters of the orifices were designed to predict the effect of the orifices’diameter on heat transfer of passage. The simulation results of the configurations with big-small diameter partition wall tend to agree with available experimental data. The results show that the heat transfer and the flow resistance both decrease with the diameter of the hole in the configuration with the same diameter partition wall. The heat transfer of the configuration with big-small diameter partition wall is better than that of the same diameter partition wall when the total flow area of holes is constant.
