In order to improve the efficiency of solving marine engineering related problems,and to provide reference for the design of the physical wave generator,the FLUENT software was used to simulate the process of wave generation and absorption in a wave tank. In the simulation,the motion conditions of the swinging-plate wave generator were defined by the user defined function UDF and the fluid motion was realized by employing dynamic mesh technology. The reflection of the wave was eliminated by the method of setting porous media area and adding momentum source term of viscous drag force. The VOF method was utilized to simulate the free surface. The simulation results show that the swinging- plate wave generator proposed in this paper can be used to produce a stable linear wave in the numerical flume. The periodic error is small enough to meet the requirements of the simulation experiments. The wave absorption method of momentum source term with a viscous drag force in a porous media area is effective enough to eliminate the reflected wave from the end wall of the tank.
