In the purpose of overcoming the shortages of physical model experiment, such as high investment and less similarities with the prototype,numerical models are used in the research of hydraulics. Based on the principle of wave generation in physical flume, the simulation of wave generator is presented by setting the movement border as a wave generator in the FLUENT, and the numerical simulation of the regularly two-dimensional wave is realized. It is also being recognized on the change of the wave height which varies according to the movement cycles, the vibration amplitude and the coordinate of the wave generator. The analysis of wave feature indicates that the numerically generated waves are comparable to the waves formed by physical wave generator. Using this method, the irregularly two-dimensional wave and random wave can also be realized by changing the boundary conditions.
