• Grid dependence in Navier-Stokes solution for free surface flows around a ship hull is investigated through numerical experiments. A Navier-Stokes solver used is a multigrid, finite-volume code with the artificial compressibility approach. Convection terms are evaluated by the third order upwind scheme based on the flux difference splitting. Time integration is carried out by the Runge-Kutta scheme. Nonlinear free surface conditions are implemented and a computational grid is re-generated to follow the free surface deformation. Free surface viscous flows around a Series 60 (Cb=0.6) hull are computed by the solver using three grids with different grid density. Solutions are compared with each other and with experimental data and grid dependence of solutions is discussed.
