| 摘 要： | 在非结构化网格基础上,采用三阶精度的三步有限元方法离散N-S方程,CLEAR-VOF方法追踪运动水体自由表面,建立了数值波浪水槽模型.模拟了远破波冲击位于倾斜底坡上直立堤的过程.对直立堤上波压力和堤前流场的数值结果与模型实验结果做了比较.结果表明,远破波波浪力和流场的数值结果同PIV实验结果吻合较好,该数值波浪水槽模型可较好地模拟远破波的破碎冲击过程.

| Abstract: | Based on the unstructured-grid approach,this paper presents a numericalwave flume mode,l in which the Navier-Stokes equation is discretized using the three step finite element method(FEM) and the free flow surface can be captured by the Computational Lagrangian Eulerian. A dvection Remap and the Volume of the Fluid(CLEAR VOF) method.This CLEAR VOF FEM model is used to smiulate the mipinging process by broken wave on the vertical break water built on a mild slope.The result shows that the simulated breaking wave force and flow field are in good agreement with the particle miage velocimetry PIV data,which indicates the applicability of the CLEAR VOF FEM model. |
