| 摘 要： | 以N-S方程为控制方程,采用VOF方法追踪自由面,通过在动量方程中添加附加源项的方法,发展了黏性流数值造波和消波的方法。基于Fluent求解器,建立了同时具有造波和消波功能的二维数值波浪水槽。进行了数值模拟分析,表明了数值造波和消波的有效性,并成功地数值模拟了在黏性流理论框架中水波与两个垂直刚性薄板相互作用产生的驻波等现象。

| Abstract: | Based on the N-S equation,the VOF method is used to track the free surface and the additive sources in the momentum equation are used to generate and absorb waves.The method of waves generating and absorbing in the viscous fluid is presented.The two-dimentional numerical wave flume which can both generate and absorb waves is obtained by use of the Fluent solver.The validity of waves generating and absorbing is numerically confirmed.The reflection and transmission of water waves past two vertical barriers are further considered,and some phenomenons(such as standing waves) are numerically simulated successfully under the viscous fluid theory. |
