摘　　要：对进气孔、扰流柱和出气孔个数之比为1∶4∶1和1∶6∶1的2种典型层板冷却结构的流体流阻特性进行了数值分析与试验研究。分析结果表明,在雷诺数相同的情况下,161型层板的流阻较141型层板的小;将计算结果与试验结果进行了比较,二者符合良好。The numerical analysis and experimental investigation of flow resistance characteristics were conducted on two typical lamiUoy models which ratio of inlet hole, pin-fin and outlet hole were 1： 4：1 and 1： 6： 1. The results show that the flow resistance of the Model 161 is smaller than that of Model 141 at the same Reynolds number. By compari son, the results of calculation are in accord with the experimental data.
