Abstract

Abstract:

A progressive displacement BEM is proposed for treating the impact of rigid body with an inviscid and incompressible fluid. This method not only gives full play of BEM advantages to semi infinite fluid space problems, but also has a good convergence. Two examples of an impacting cylinder and an impacting wedge into initially calm water are presented. The results show that the proposed method is effective.

Key words: fluidst ructure impact, boundary element method, potential problem, fluidst ruc ture interaction
