Abstract: 

This paper is presented to compute the wave-making resistance of an ellipsoid submarine, using boundary element method (BEM), in which the body surface and free surface are discretized into hyperboloidal elements. The fundamental solution of the governing Laplace's equation was obtained using Green's function via boundary integral equation. The linearized free surface boundary condition was applied and the unknowns of the doublet on the body and source on the free surface were obtained by solving the discretized equations. Then, the numerical results of pressure, wave-making resistance, and wave elevation were determined. We presented the results for the Wigley hull and for the submerged moving ellipsoid shape of the submarine UV11. The validity of the numerical results was examined by comparing it with experimental results.
