介绍了以封闭壳体内的旋转圆盘系统模拟实际叶轮机械中叶轮轮面在机壳内旋转时所受摩擦阻力的实验。实验结果表明，在一定的间隙范围内，随着间隙比的增加，旋转圆盘上的粘性力矩增加，而且旋转圆盘上的粘性力矩随圆盘粗糙度的增加而增加，随流场温度的增加而降低。
An experiment was carried out to simulate the friction resistance of the impeller in the closed rotating disk system when the impeller was rotated in the housing. The experimental results show that the viscous moment increases on the rotating disk with the increase of the clearance ratio within a certain gap range, and the viscous moment increases with the increase of the disk roughness with the increase of the clearance ratio, Increase and decrease.
