摘　　要：运用罚函数有限元方法计算了间隙流场内速度的分布，并计算了在小间隙比时光滑旋转圆盘上的粘性力矩．通过实验，测量了封闭壳体内旋转圆盘上的粘性力矩．实验数据与计算结果相符．Penalty finite element method is used to calculate the flow field induced by an enclosed rotating disk.The frictional loss of the disk has been studied both experimentally and numerically. The numerical results agree with the test data.
