Abstract: This paper deals with the treatment of time accurate calculations of inviscid incompressible flows with free surface by using dual time stepping based on an artificial compressibility formulation. The flow field and the free surface location are calculated by coupling the free surface kinematic and dynamic equations with the equations of motion for the flow under free surface. Second-order time-differencing scheme and the cell-centered finite volume scheme based on flux difference splitting are used for these calculations.
