描述了二维溢出破碎波的数值模拟模型。它源自先前的一个模型，而该模型又从Cointe和Tulin的稳定破浪理论中汲取了其基本思想。与前一个模型相比，现在的模型是局部的，即破浪的起始、延伸和几何形状是通过水面的局部形状来确定的。通过对边界条件的修改，该模型已在为模拟船舶流动而开发的RANSE代码中实现。这就产生了一种简单而有效的方法来再现断路器对底层气流的影响。所得到的代码已被用于模拟水下水翼的流动。数值结果与之前的模型和Duncan的实验数据进行了比较。
A numerical model for the simulation of two dimensional spilling breaking waves is described. It is derived from a previous model which, in turn, takes its underlying ideas from the Cointe and Tulin theory of steady breakers. With respect to the former model, the present one is local, i.e., the inception, extension, and geometry of the breakers are determined through the local shape of the water surface. The model has been implemented in a RANSE code, which was developed for the simulation of ship flows, through a modification in the boundary conditions. This yields a simple and effective way to reproduce the breaker’s influence on the underlying flow. The resulting code has been used to simulate the flow past a submerged hydrofoil. The numerical results are compared with those of the previous model and with the experimental data obtained by Duncan.
