A numerical wave tank has been established based on the SPH method. With the theory of Riemann, the particle pressure and velocity at the end of the tank are modified by introducing the wave dissipation coefficient and damping coefficient. The numerical result shows that the energy of the particles in the wave absorbing layer region decreases rapidly and gently. The wave reflection at the end of the tank is solved successfully. By comparing the wave surface of the fixed point in the numerical tank with the theoretical surface, it is verified that the method of pressure wave elimination is a good choice in simulating the two-dimensional numerical wave tank.
