In this study, the SHIPFLOW steady state RANS code is extended to include the computation of free surface flows. A volume-of-fluid (VOF) surface capturing method is used to locate the water-air interface. A void fraction transport equation is introduced to the system of equations and solved in a coupled manner. The finite volume formulation is used and the convective fluxes discretization is based on the first order Roe type flux difference splitting algorithm. Various higher order corrections were tested, however results from only selected ones are presented here.
