圆盘摩擦损失的降阻研究

Study of Reduction-in Frictidnal Loss of Rotating Disk

本文根据间隙流场的特点,提出了在旋转圆盘与外壳间流场插入一能自由旋转圆盘的减阻方案,并进行了数值计算和实验研究。数值计算与实验结果均证明该措施有利于降低旋转圆盘上的摩擦损失功率。

According to the velocity distribution the flow field, a hypothesis that a rotating inserter between the disk and the wall will reduce the frictional loss of rotating disk is provided. The method has been studied experimentally and theoretically. The results of the numerical calculation and experiment verify that it is of great value to us.
