A comprehensive review of the local scour due to vortical flow around a cylindrical bridge pier under steady current is presented in this paper. The mechanism of the formation of vortices, the size, velocity and strength of horseshoe vortex (HSV), formation of the HSV by the separation of laminar and turbulent boundary layer and the scour around a cylindrical pier due to vortices have been presented. The complexity involved in the scour-related calculations, and the scope for future research are discussed in the last section.

安装在平板上的垂直圆柱体上的马蹄涡的流体动力学及其对圆柱体冲刷的影响

本文对在恒流作用下圆柱桥墩周围涡流引起的局部冲刷进行了全面综述。提出了涡旋形成的机理，马蹄涡旋（HSV）的大小，速度和强度，层流和湍流边界层分离形成的HSV以及由于涡旋引起的圆柱墩周围的冲刷。最后一部分讨论了与冲刷相关的计算所涉及的复杂性以及未来研究的范围。
