A study on nonlinear wave-body interactions due to impulsive motion (2nd Report)

Abstract

The water entry problems of a wedge with constant vertical velocity are studied by using a boundary element method. The computational models about jet flow are proposed and these are applicable to the problems for wedges with various dead rise angles. In addition, it turned out that the singularities at a bottom vertex were apt to lose the precision of local pressure values. Accordingly we introduce the analytical description of the flow in a local domain around the vertex. These solutions can be determined by solving integral equations with the solutions in the other domain.
