Transport Noise effect on Kelvin-Helmholtz instability
The Kelvin-Helmholtz instability is an instability occurring at the interface of two fluids in shear flow. We numerically investigate the effect of transport noise on this instability by performing numerical simulations in the 2D case, by means of the point vortex method. We study the dissipation properties of small-scale transport noise, to test if transport noise acts as a stabilizing factor. In particular, we investigate three different scenarios: inviscid and viscous fluid without transport noise, and inviscid fluid perturbed by transport noise. Our results show that the transport noise effectively act as a viscosity term.
