It has been found that vortex shedding can occur from long cylinders at small angles of yaw, i.e. in near‐axial flow. The range of Reynolds number over which this can take place has been determined for yaw angles between 0° and 10°. Results for vortex‐shedding frequencies are also presented, and compared with existing data for larger yaw angles. It is suggested that the phenomenon may be relevant to turbulence‐generation mechanisms in thick axisymmetric turbulent boundary layers.

近轴流中细长圆柱体的涡流脱落

已经发现 涡流长圆柱体会以较小的偏航角（即近轴流）发生脱落。范围雷诺数对于0°到10°之间的偏航角，已经确定可以进行此操作。还给出了涡流脱落频率的结果，并将其与现有数据进行了较大偏航角的比较。建议该现象可能与湍流产生 轴对称的机理 湍流边界层。
