Abstract: Slope is a commonly coastal and reservoir protection engineering structure that is used to provides defense against the invasion of land from waves and currents. Based on the computational fluid dynamics software Fluent, a two-dimensional wave numerical flume was established. Under the condition of regular waves, the wave overtopping process of smooth slopes and slopes with fences was simulated. Results show that the fence panel exhibits a mitigation effect on the surging water body and can effectively improve the wave absorbing ability of the slope. Comparing the over-the-top wave volume of slopes with different gradients and different panel spaceings, the results show that the slope designed herein has a significant wave-eliminating ability under the conditions of small gradient and small spacing.

Key words: Fluent software；numerical simulation, fence panels, regular wave, overtopping wave
