The numerical wave flume of the viscous fluid based on the momentum source method

LI Ling, LIN Zhao-wei,YOU Yun-xiang, MIAO Guo-ping(School of Naval Architecture,Ocean & Civil Engineering,Shanghai Jiao Tong University,Shanghai 200030)  
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.
