Abstract
This study considers a submerged body moving from rest to a constant speed in the nonlinear free surface for a truncated water region. A higher order boundary element method (HOBEM) with a fourth order Runge-Kutta time stepping scheme is used to simulate the wave evolution processes and predicts the wave resistance and lift forces acting on the submerged body. The time domain simulation approach is used to obtain a fully nonlinear steady state wave system. The author chooses a simple shape body, i.e. sphere, which provides analytic solutions and other numerical solutions so that a rational comparison can be made. The Orlanski's open boundary condition is used both downstream and upstream of the free surface. The linear and fully nonlinear surface waves induced by a submerged moving body are calculated. It was found that the present techniques provide more accurate results than the numerical analysis method currently employed.
