vortex pair

基本解释

The vortex pair induced by the separation is developing downstream into the wake of the after-body.
由分离形成一对方向相反、强度相等的旋涡向下游拖至尾迹区；
Ultimately, the separation vortex pair enter and mix with the jet at far field to form the counterrotating vortex pair in the jet body.
证实绕流分离旋涡最终在射流的顺流贯穿段进入射流主体，混合形成射流主体内的主反向旋转涡对。
The result shows the periodic characteristics of microjet flow field including vortex pair evolution, immigration and dissipation process.
模拟结果显示了微射流的产生、形成、发展与耗散过程以及微射流的卷吸特征等。
