  • Topological structure of a slender crossflow was discussed with topological analysis.It is pointed that the development of slender vortices leads to the change of topological structure about cross flow,and a critical flow pattern will appear.There is a high-order singular point in this critical flow pattern.And the index of the high-order singular is -3/2.The topological structure of this singular point is instable,so bifurcation will occur and the topological structure of flowfield will be changed by little disturbance.
