Based on the discrete vortex method, a conformal mapping technique is used to solve Karman vortex street-airfoil interaction.
本文利用保角变换，用离散涡方法求解了卡门涡街与翼型的相互作用。
The emission frequency of the Karman vortex street occurred in series from the blades and tongue is varing with the running condition.
将流程泵叶轮叶片和压水室的隔舌看作旋涡发生体，在不同运行工况下在叶片后缘以及隔舌两侧串联发生的卡门涡街的发射频率是不同的。
There are two shedding modes along the slender axes when the angle of attack is very high. The Karman vortex shedding region is located in afterbody while the nose vortices region is near the apex.
在迎角很大时细长旋成体背部流场沿轴向通常有两个截然不同的区域，其中卡门涡脱落区域位于后体，而头涡区域靠近旋成体头部。
