在雷诺数较小的情况下，计算了平面壁面附近圆柱体的二维绕流。对于平行于壁面平移的圆柱体，圆柱体上的扭矩为零;同样，对于旋转的圆柱体，力为零。这些结果，这是令人惊讶的，当与相应的球体相比，证明，然后进一步研究使用润滑理论。我们还考虑垂直于壁面的运动，从而可以讨论圆柱沿斜面下落的行为。此外，流线型模式进行了描述。
The two-dimensional flow around a cylinder that is near a plane wall is calculated assuming that the Reynolds number for the flow is small. For a cylinder translating parallel to the wall, the torque on the cylinder is zero; similarly, for a rotating cylinder the force is zero. These results, which are surprising when compared with corresponding ones for a sphere, are proved and then examined further using lubrication theory. We also consider motion perpendicular to the wall, allowing us to discuss the behaviour of a cylinder falling down an inclined plane. In addition streamline patterns are described.
