这篇论文基于 inviscid 和 imcompressible 液体和无旋的流动在液体 / 结构影响上论述工作的评论。焦点在和边界元素方法(BEM ) 的速度潜力理论上。充分非线性的边界条件在未知免费表面和动人的身体的弄湿的表面上被强加。评论包括(1 ) 在常数或规定变化速度的身体的垂直、倾斜的水入口，以及免费秋天运动，(2 ) 液体微滴或列影响以及波浪影响身体，(3 ) 膨胀身体的类似答案。它盖住二维(2D ) ， axisymmetric 并且三维(3D ) 盒子。在数字模拟使用的关键技术被构画出，包括 multivalued 上的网孔产生免费表面，为扩展域的拉长的坐标系统，压力的相互的依赖和身体打手势的为去耦的辅助函数方法，并且为喷气或薄液体电影的处理在影响期间发展了。

This paper presents a review of the work on fluid/structure impact based on inviscid and imcompressible liquid and irrotational flow. The focus is on the velocity potential theory together with boundary element method （BEM）. Fully nonlinear boundary conditions are imposed on the unknown free surface and the wetted surface of the moving body. The review includes （1） vertical and oblique water entry of a body at constant or a prescribed varying speed, as well as free fall motion, （2） liquid droplets or column impact as well as wave impact on a body, （3） similarity solution of an expanding body. It covers two dimensional （2D）, axisymmetric and three dimensional （3D） cases. Key techniques used in the numerical simulation are outlined, including mesh generation on the multivalued free surface, the stretched coordinate system for expanding domain, the auxiliary function method for decoupling the mutual dependence of the pressure and the body motion, and treatment for the jet or the thin liquid film developed during impact.
