NUMERICAL MODELING OF 2-D WATER IMPACT IN ONE DEGREE OF FREEDOM

Abstract

The Reynolds-averaged Navier-Stokes equations are solved in a commercial flow solver to compute the water impact of two-dimensional simple geometries, entering the water in vertical motion of constant speed. The simulation shows better agreement with measurements than classical theories and potential flow solutions. Surface tension and viscosity are shown to be negligible in this application, but gravity is important. A tilt of wedges introduces an asymmetry in the flow increasing maximum pressures as compared to the perfectly symmetric case.
