本文研究了水平同心圆筒间层流的近似速度分布，其中内圆筒只作旋转运动，而不考虑系统完全充满时的液面高度。层流的稳定性取决于Di Prima使用的参数Sandd 0/das，其中d 0是零速度表面到内圆柱的距离，d是差距的宽度。研究了不稳定性引起的二次运动，发现当环空充满液体时，由于两个圆筒反向旋转，在内圆筒和d_0之间产生的旋涡的波长与d_0/d相同时的波长一致。
The approximate velocity distributions for laminar flow between horizontal concentric cylinders with the inner cylinder only rotating have been studied for liquid levels other than when the system is completely full. The stability of the laminar flow has been shown to depend on the parametersSandd0/das used by Di Prima, whered0is the distance of the surface of zero velocity from the inner cylinder anddis the width of the gap. The secondary motion resulting from instability has been investigated and the wavelength of the vortices produced between the inner cylinder andd0agrees with that for the same value ofd0/ddue to rotation of both cylinders in opposite directions when the annulus is full of liquid.
