VOF方法模拟波浪槽中二维非线性波

造波板运动生成非线性波问题是研究物体与波浪非线性相互作用的典型例子。本文研究了用ＶＯＦ方法模拟波浪水槽生成非线性波（孤立波和椭圆余弦波）的问题，为实现造波板在计算中可以做穿越网格的大幅值运动，本文采用在压力迭代中调整造波板邻近单元中压力来满足造波板上流体运动条件。对开路边界条件和自由表面与物面交点处边界条件也提出了处理方法，计算结果与实验结果和解析结果进行了对比。

Numerical Simulation of Nonlinear Wave Generated in Wave Flume by VOF Technique

The nonlinear wave generated by wave-making board is a typical problem of the interactions of nonlinear wave with bodies.This paper researched this problem by applying the VOF technique.In order to allow the wave-making board to move through grid cells in computations,the boundary condition on the board surface was satisfied by adjusting the water pressure in the cells near the board during the prosess of pressure iteration.This paper also deals with the problems of open boundary condition and the boundary condition on the intersection of body surface and free surface.The comparisons were made between numerical and experimental results.
