Numerical Analysis of the Neumann-Kelvin Wave Problem for an Actual Ship

Abstract

The numerical analysis of the boundary value problem with linearized free surface condition (Neumann-Kelvin problem) is presented. The wave resistances of Wigley model and a high speed container ship model (SR 138 model) are calculated. The results are compared with the experimental values and some theoretical solutions based on Michell's theory, double model source method and low speed theory. The solutions of the Neumann-Kelvin problem for Wigley model coincide fairly well with the experimental values. However, for the SR 138 model they are smaller than the measured values. These discrepancies are discussed by the comparison between calculated and measured wave contours.
