Based on Navier-Stokes equations to describe the motion of incompressible fluid,the volume of fluid (VOF)method is adopted to track the free surface.In the second development of FLUENT,the source term expression of each functional area is added to the momentum equation to realize the momentum source wave and the wave elimination.In this paper,the flow field and wave pressure of the different sections of the anti-wave wall under the action of second-order Stokes wave are simulated,and the calculated results are compared with the physical model test data,and the results are in good agreement.Comparing the results of the numerical calculation of the wave pressure of the vertical and curved walls,it can be found that the maximum pressure on the arc wall is significantly greater than the vertical wall in the case of the same water level and the wave elements,and the maximum pressure occurs in the arc part which should be strengthened in order to ensure the overall stability of arc crown wall.
