描述了一种计算流体动力学（CFD）方法求解极端非线性自由表面问题。该算法是基于CIP方法和波体相互作用的多相计算进行了笛卡尔网格。数值模拟结果的两个实验问题，我们已经进行。第一个是船波相互作用的问题，并进行了实验，使用的数学船舶模型在拖曳水池。对自由水面变形、甲板和竖壁压力以及波浪诱导的船舶运动进行了计算和试验对比。第二个是入水问题，实验是在一个圆柱体上进行的，圆柱体从空气中落入静止的水面。除了这个3-D的问题，2-D的水进入问题的结果也验证了代码。笛卡尔网格波浪-船舶相互作用入水
A CFD approach for extremely nonlinear free surface problems is described. The algorithm is based on the CIP method and the multi-phase computations on wave-body interactions are carried out on a Cartesian grid. Numerical simulation results are presented on the two experiment problems we have conducted. The first is a ship-wave interaction problem, and the experiment was carried out using a mathematical ship model in a towing tank. Comparisons between computation and experiment are made on the deformation of the free surface, the pressures on the deck and vertical wall, and the wave-induced motions of the ship. The second is a water entry problem, and the experiment was performed on a circular cylinder dropped from air into a still water surface. Besides this 3-D problem, results on a 2-D water entry problem are also presented for verification of the code. Cartesian grid Wave-ship interaction Water entry
