This paper presents numerical simulations of flows around a ship with and without propeller effect. Viscous flows are simulated by solving the Navier-Stokes equations using a control volume method with a global conservation law. A propeller effect is considered by applying equivalent body force distribution. The propeller forces are estimated by an infinitely bladed propeller theory developed by Yamazaki. Since we consider a propeller rotating effect, the NS solver is modified in order to compute flow domain of both sides. A tanker hull form is used for numerical simulations. Computed results are compared with experiment data and we thus show the effectivenes of the present method. Further, twin-propelled ship hull flows are simulated in order to show the capability of the application of the present method.
