将进行数值模拟，以预测与平面尾迹和圆形喷流有关的三维有组织的涡旋结构。需要解决的问题是这些涡旋结构的稳定性机制和三维相互作用。数值过程基于拉格朗日涡动力学。这些方法不会引入数值网格效果。重点放在最终可能被用来控制尾流和喷流稳定性的机制上。
英文摘要
Numerical simulations will be carried out to predict organized vortex structures in three dimensions relevant to plane wakes and round jets. Issues to be addressed are stability mechanisms and three-dimensional interactions for these vortex structures. The numerical procedure is based on Lagrangian vortex dynamics. These methods do not introduce numerical grid effects. The focus is on mechanisms which might ultimately be used to control the stability of wakes and jets.
