Abstract
The Rankine-source method has been combined with an integral method for boundary layer and wake so as to investigate the influence of boundary layer and wake on the free surface flow around a ship model. The head loss due to viscosity has been taken into account in the equation of the boundary condition on the free surface. The numerical solution of the free surface flow with the boundary layer and wake around 6 m long Wigley model has been obtained with aid of the technique of matrix calculation for source densities on the panel array on the hull surface along with center plane in wake and on the free surface. The computed results as for pressure distributions on the hull surface, wave profiles along the hull side and pressure, frictional and total resistances have been shown in comparison with measurements. They display good results by considering the existence of boundary layer and wake around the hull of the model.
