Islands in stable fluid equilibria

Analysis of PDEs 2023-05-19 v1 Fluid Dynamics

Abstract

We prove that stable fluid equilibria with trivial homology on curved, reflection-symmetric periodic channels must posses "islands", or cat's eye vortices. In this way, arbitrarily small disturbances of a flat boundary cause a change of streamline topology of stable steady states.
