Abstract: 
This paper is presents the computation of the wave-making drag of underwater vehicle by boundary element method (BEM). The method is employed constant strength doublet and source distributions on each quadrilateral element representing the body and free surface. Using Green's function, boundary integral equation is constituted for all elements by a matrix form to determine the potential on each element, and then calculate the pressure and wave-making drag at different vehicle speeds and water depths. The computed results indicate that the present method is in good agreement with other results and, its results are shown that the method is more capable and powerful tool for prediction and analysis of wave-making drag of underwater (UV11) vehicle.
