对同心旋转圆柱间流体的稳定性进行了研究，结果表明，当只有内圆柱旋转时，当超过一定雷诺数时，流动变得不稳定。当外筒只旋转时，就前一种情况所产生的扰动而言，流动是稳定的，但一旦流动的雷诺数超过一定值，就会出现湍流。本实验的目的一方面是测量两种情况下两缸间的扭矩反作用力，以找出离心力对湍流的影响，另一方面是找出从流线过渡到湍流的临界雷诺数。该装置如图1所示。
The stability of fluid contained between concentric rotating cylinders has been investigated and it has been shown that, when only the inner cylinder rotates, the flow becomes unstable when a certain Reynolds number of the flow is exceeded. When the outer cylinder only is rotated, the flow is stable so far as disturbances of the type produced in the former case are concerned, but provided the Reynolds number of the flow exceeds a certain value, turbulence sets in. The object of the present experiments was partly to measure the torque reaction between two cylinders in the two cases in order to find the effect of centrifugal force on the turbulence, and partly to find the critical Reynolds numbers for the transition from stream-line to turbulent flow. The apparatus is shown diagrammatically in fig. 1.
