Numerical simulation of wave impact pressure acting on bow in head sea

Abstract

The paper describes the simulation method for the wave impact pressure acting on a bow section, where the boundary element analysis on a two-dimensional water impact problem is applied. Computed results are compared with those by the MPS method, a kind of particle methods. Good agreement is recognized in both the free surface flow and the time histories of pressure. The numerical description using the boundary element is properly-validated in the water entry, the water exit, the jetting, the nonviscous flow separation, the trapped air, and so on.
