本文采用基于不可压缩雷诺平均N-S方程和k-ε方程的数值波浪模型，计算了孤立波对位于平坦海滩上不同高程的理想化海滨房屋的影响。自由面的位置由流体体积法(VOF)重建。用波浪爬高试验数据和直立墙上波浪力的解析解对该模型进行了验证。给出了理想房屋的波浪型、作用力和倾覆力矩的时程曲线，并进行了分析。还研究了波浪力和倾覆力矩随理想海滨房屋高度的变化情况。
In this paper, a numerical wave model based on the incompressible Reynolds-averaged Navier–Stokes (RANS) and k–ε equations is used to estimate the impact of a solitary wave on an idealized beachfront house located at different elevations on a plane beach. The locations of the free surface are reconstructed by volume of fluid (VOF) method. The model is satisfactorily tested against the experimental data of wave runup, and the analytical solution of wave forces on vertical walls. The time histories of wave profiles, forces, and overturning moments on the idealized house are demonstrated and analyzed. The variations of wave forces and overturning moments with the elevation of the idealized beachfront house are also investigated.
