A finite volume method, based on artificial compressibility scheme, to solve the nonlinear ship wave resistance problems is presented. The equivalent body force method is adopted in a viscous/potential flow coupled scheme to evaluate the propeller-hull interaction problem. The composite grid technique is incorporated to enhance grid generation flexibility for treating complex geometry. The present results of several conditions for modem commercial hull forms have been validated by a proper comparison with experimental data. It is demonstrated that the present method can be applied to the evaluation of hull form with required accuracy for practical use.
