Level-Set Simulation of Viscous Free Surface Flow Around a Commercial Hull Form

The viscous free surface flow around a 3600 TEU KRISO Container Ship is computed using the finite volume based multi-block RANS code WAVIS developed at KRISO. The free surface is captured with the Level-set method and the realizable kappa-epsilon model is employed for turbulence closure. The computations are carried out at model scale. In order to obtain an accurate free surface solution and stable convergence the computations are performed with a proper fine grid refinement around the free surface and with an adoption of implicit discretization scheme for the Level-Set formulation. In all computational cases the present results show a good agreement with experimental measurements.
