Numerical investigation of shear-flow free-surface turbulence and air entrainment at large Froude and Weber numbers

We investigate two-phase free-surface turbulence (FST) associated with an underlying shear flow under the condition of strong turbulence (SFST) characterized by large Froude ( $Fr$ ) and Weber ( $We$ ) numbers. We perform direct numerical simulations of three-dimensional viscous flows with air and w...
