Numerical simulation of a viscous vortex ring interaction with a density interface
Abstract
The incompressible Navier-Stokes equations are solved for the interaction of a vortex ring with a density interface. Axisymmetric and three-dimensional calculations are performed for a range of interface strengths, for both Boussinesq and finite-amplitude density jumps. Secondary and tertiary ring formation, vortex rebound, and backflow jets are some of the features observed in the interactions.
