| 摘 要： | 本文应用ＶＯＦ方法研究了孤立波翻越直立方柱流动的全过程。用人工压缩法和差分法求解二维Ｎａｖｉｅｒ－Ｓｔｏｋｅｓ方程，用施主－受主法求解流体体积函数控制方程。通过数值计算得到了孤立波翻越直立方柱的流场和压力值，并成功地模拟出波浪涌顶，水柱喷射，冲击和界面破碎的过程。

| Abstract: | In this paper the VOF method is introduced to simulate the flow of waves overtopping an erect quadrate column. The finite difference method and artificial compressibility technique are used to solve the full two-dimensional Navier-Stokes equations, and a donor-acceptor scheme is adopted to discretize the governing equation of a function of volume of fluid. Numerical results of a solitary wave overtopping an erect quadrate cylinder are obtained, including the flow field, pressure and surface profile,as well as wave accumulating, wave run-up, jet, impinging,breaking and reflection. |
