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

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.
