| 摘 要： | 针对滑坡涌浪灾害中波浪的产生和传播分析至关重要的问题,利用FLUENT软件平台,提出了边界造波的数值方法,并通过二次开发实现了二阶Stokes波的数值模拟。该边界造波法以不可压缩粘性流体的Navier-Stokes方程和追踪自由面的VOF法为基础,借助FLUENT软件中的UDF功能定义了入射边界处波浪的速度和波形解析表达式,从而模拟了二阶Stokes波的产生和传播。计算结果表明,该数值水槽能有效可靠的模拟弱非线性波浪。这为后续模拟由滑坡涌浪所产生的波浪提供了一定的研究基础。

| Abstract: | In the study on the effects of landslide-induced waves on the downstream dam,the estimations of wave generation and wave propagation are important. Aiming at this type of hazard problem,this paper presents a numerical approach of wave-generation method of defining inlet boundary conditions for simulating the second-order Stokes wave through the redevelopment in FLUENT code. This wave-generation method is based on the Navier-Stokes equations and VOF method of tracing the free surface. The study is carried ou... |
