A summary of water entry problem of a wedge based on the fully nonlinear velocity potential theory

摘要：

This paper presents a comprehensive study of water entry of a wedge through numerical simulation. The mathematical model is based on the assumptions of inviscid and incompressible liquid and irrotational flow, while the solution procedure is based on the boundary element method for the complex velocity potential. In particular, the problem is solved in the stretched coordinate system. The wedges considered include a symmetrical wedge, an asymmetrical wedge and twin wedges, and the motions considered include vertical water entry and oblique water entry at prescribed velocity, and free fall motion in one and three degrees of freedom.
