On stagnation points and streamline topology in vortex flows

Aref, Hassan; Brøns, Morten

Journal of Fluid Mechanics — 1998, Volume 370, pp. 1-27

of the stagnation point in a flow produced by three vortices with sum of strengths zero is found. Using topological arguments the distinct streamline patterns for flow about three vortices are also determined. Partial results are given for two special sets of vortex strengths on the changes between these patterns

On Stagnation points and streamline topology in vortex flows

Aref, Hassan; Brøns, Morten

The problem of locating stagnation points in the flow produced by a system of N interacting point vortices in two dimensions is considered. The general solution, which follows from an 1864 theorem by Siebeck, that the stagnation points are the foci of a certain plane curve of class N-1 that has all
