| 摘 要： | 按普朗特边界展理论，将圆柱面上再附边界层流动表示成级数的形式，并根据实验所测圆柱表面上的压强分布导出再附边界层外边界上的流速分布，取有限项级数解的形式解出了圆柱表面上再附边界层内的流速分布及流动再分离点。

| Abstract: | Based on Prandtle boundary layer theory, a series was engaged in present paper to describe the reattachment boundary layer flow over a circular cylinder. Referenced the experimental data of the pressure distribution on the cylinder wall, the finite series solution was obtained. The series solution shows that the reattachment boundary layer has its separate point (e.g. re-separate point) else on a curved surface and that if the layer reattaches suitably on the surface, the re-separate point will be pushed downstream of the cross section of the circular cylinder. |
