Numerical Evaluation of Double and Single Integral Versions of the Green Function for Wave Resistance Determination Conference Paper uri icon


  • Rayleigh damping is introduced into a potential flow based method in order to improve wave resistance determination. The problem is modelled using Kelvin sources with a translating speed. A dissipative 3D Green function is applied. The inclusion of Rayleigh damping removes the singularity associated with conventional Green functions. However, in this study it is shown that this benefit is purely mathematical and that the numerical complexity associated with the integration of a double integral is still best overcome by separating the double integral into two single integrals. The wave resistance for submerged ellipsoid is determined using a panel method.
