We present here a numerical method for solving the free surface flow around a ship at forward speed in calm water. The fluid is assumed to be Newtonian and the Reynolds‐averaged Navier‐Stokes equations are solved by a finite difference method. Modelization of turbulence is achieved by the algebraic model proposed by Baldwin and Lomax. Fully non‐linear free surface conditions are satisfied in the model and a method to avoid the incompatibility between free surface conditions and no‐slip conditions at the waterline is proposed. Numerical results obtained for a Wigley hull are compared with experimental results.
