Abstract: On the one hand, the deformation and breaking of near-shore waves affect the transportation of water and sediment, and on the other hand, it is of guiding significance for wave elimination and revetment. In this paper, a 3-dimensional hybrid turbulence simulation model is proposed. Laminar flow mode is adopted in the wave-making region, and velocity wave-making is carried out at the boundary through the User Defined Function(UDF) developed based on fluent. This method can control the volume fraction of water by precise interpolation according to the known wave height under the condition of given inlet velocity. In the wave propagation region, large eddy simulation (LES) is used for simulation research, and in the wave elimination region, RANS model with the porous media wave absorber is used for wave elimination. The model uses the VOF method to capture the free surface changes in the process of wave breaking. This paper carried out simulation studies on the regular wave (M1) with a wave height of 5.5cm, the regular wave (M3) with a wave height of 13.5cm, the unidirectional irregular wave (U1) with a TMA spectrum with an effective wave height of 7.75cm and the multidirectional irregular wave (B5) with an effective wave height of 19cm. Simulation results show that the proposed model can accurately simulate the wave propagation in the process of refraction and diffraction phenomenon, and be able to catch the waves of the free surface in the process of change, broken for 3D wave propagation and broken numerical simulation provides a method of simulation.
