概要

A new method calculating diffraction pressure over a ship running in oblique waves is presented. The method is constructed based upon the same assumption as convetional strip theory (NSM) except for exact formulation on body boundary condition and inclusion of x-derivative term of the velocity potential in the free surface condition. Through the boy boundary condition effect of the variation of the wave orbital velocity along the body surface is taken into account whereas most of conventional strip method calculation fail. Numerical scheme is presented following Ursell-Tasai method. Results obtained by the present method are compared with experimental results to show that they are in good agreement for most of running and incident conditions in waves.
