Abstract

A boundary element method (BEM) is applied to the computation of the steady, incompressible flow around propellers. The method is based on Morino's^ formulation for the disturbance potential. The method uses constant dipole and source singularity distributions on flat or hyperboloidal panels. The paper discusses the basic choices made to evaluate the matrix of influence coefficients and the use of direct and iterative solvers in the solution of the system of equations. It is shown that the use of hyperboloidal elements improves the convergence of the numerical solution. 1 Introduction In recent years the boundary element method (BEM) has become in the ship hydrodynamics community an
