Kelvin–Helmholtz instabilities at interface of air and water in pond

The Kelvin–Helmholtz instability (after Lord Kelvin and Hermann von Helmholtz) can occur when there is velocity shear in a single continuous fluid, or where there is a velocity difference across the interface between two fluids. here are some detail about simulation Inlet air velocity = o.5 m/s Water and air density default VOF is used Primary phase: air Secondary Phase: water SimpleC algorithm Volume fraction: Compressive Time step : 3e-4 CFL = u*delt T/deltx
