Vortex-dipole surface wave interactions in deep water
We describe a simple experiment to study the interaction between surface waves and vertical vorticity in the deep water regime. The vortex circulation introduces dislocations on the wavefront which can be explained by the advection of the propagating wavefront, due to the fluid motion. The analogy between wave vortex interactions and the Aharonov-Bohm effect is explored further by considering the case of surface waves interacting with a vorticity dipole.
