| 摘 要： | 通过对离心叶轮外侧间隙中泄漏气体流动的分析，给出了速度分布，利用Ｇｏｌｄｓｔｅｉｎ由旋转圆盘实验得出的对数壁面率去处理叶轮外侧面的摩擦应力分布．求解边界层动量积分方程，计算了叶轮外侧面的摩擦损失．将计算结果与实验结果进行了比较，并对一台实际离心压缩机叶轮外侧面的摩擦损失进行计算，证明文中所述的计算叶轮外侧面的摩擦损失的方法是正确的，对离心式压缩机的设计具有一定的参考价值．

| Abstract: | A velocity distribution formula is proposed for the gap between shroud or hub and casing under the turbulence condition. A logarithmic law obtained by Goldstein is used to express the wall shear stress. The boundary layer momentum integral equations are used to calculate the friction loss of centrifugal compressor. Close agreement is obtained between the calculated and measured data. |
