RELAXATION OF EULER EQUATIONS AND HYDRODYNAMIC INSTABILITIES

We present a relaxed version of incompressible Euler equations that permits foliated flows involving two velocities. These relaxed equations allow a two-phase evolution of some vortex sheets as an alternative to discontinuous solutions of Euler equations. In the case of two perfect fluids of differe...
