本文提出了一种基于CIP（约束插值剖面）方法的计算流体力学方法，用于预测强非线性海洋水动力。数值模型采用直角坐标网格进行数值求解，并采用CIP方法进行流动求解和自由表面界面捕捉。采用守恒CIP格式，对二维液体晃动问题进行了有效的界面捕捉。对于强非线性波体相互作用，笛卡尔网格方法，其中的物体表面近似分布的虚拟粒子上，处理在物体表面的边界条件。对船舶在大波浪中的运动进行了三维数值模拟。
Abstract A CFD approach based on the CIP (Constrained Interpolation Profile) method has been developed for predicting strongly nonlinear marine hydrodynamics. The numerical model uses a Cartesian grid for numerical solution and applies the CIP method for the flow solver and the free-surface interface capturing. An efficient interface capturing method by using a conservative CIP scheme is applied to two-dimensional sloshing. For strongly nonlinear wave-body interactions, a Cartesian grid method, in which the body surface is approximated by distributing virtual particles on it, treats the boundary condition at the body surface. A three-dimensional numerical simulation on a ship moving in large waves is presented.
