潜堤附近波浪场精细模拟的PLIC-VOF模型

Fine simulation of wave field near submerged bars using PLIC-VOF model

摘要: 采用PLIC-VOF追踪自由面,利用无反射造波边界条件数值造波,结合有限差分方法离散求解潜堤附近水域的立面二维N-S方程,得到潜堤附近波浪场。对两种典型潜堤结构附近的波浪场进行了数值计算并与模型实验结果作了比较。比较结果表明,基于PLIC-VOF的数值方法能够有效地追踪波浪自由面并得到潜堤附近精细的波浪场。

Abstract: The purpose of this paper is to simulate the wave profile and flow field when the wave propagates the submerged bars by using the PLIC-VOF model to trace the free surface of wave and the finite difference method to solve the 2-D N-S equations. After comparing the numerical results of two kinds of submerged bars with the experimental ones,it is believed that the PLIC-VOF model used in this study is effective and can compute wave field finely.
