Abstract
A finite-difference method of the Navier-Stokes equations is developed to simulate viscous flows with a free surface around a ship. The body-fitted coordinates system which does not fit to the free surface is used in order to cope with ships of arbitrary forms easily. The nonlinear free surface condition is implemented by special method. Simulated results of free surface flows around a Wigley's hull at low Reynolds number are presented and compared with the experimental data.
