RANKINE SOURCE METHODS FOR NUMERICAL SOLUTIONS OF THE STEADY WAVE RESISTANCE PROBLEM

The steady potential flow past a body in or near the free surface of an ideal fluid is computed by superimposing the potential of triangular source panels inside the hull surface and above a part of the free surface. The free surface condition is linearized with respect to the differences between exact values and approximations of surface height and the potential there; this leads to an iteration scheme to satisfy the nonlinear condition. Based on theoretical reasoning and numerical experiments, a novel, accurate method to satisfy the radiation condition is proposed. Results for the flow past a submerged vortex and preliminary results for the Wigley parabolic hull are presented.
