Abstract

The water entry problems of a wedge with vertically constant velocity are studied by using the boundary element method. The computational models about jet flow are proposed. These are applicable to the problems for wedges with various dead rise angles and additionally make it possible to simulate the free surface evolution in the jet flow region. In predicting the pressure on the wedge, it turned out that the singularities at a bottom apex were apt to lose computational precision. Accordingly we introduce the analytical description of solutions in the local domain around the apex. We can obtain the analytical solutions matched with the numerical solutions in the other domain.
