Stepped Mound Breakwater Simulation by Using Flow 3D

Abstract

Waves action is one of the most well-known hydraulic events in history. When waves hit rocks or other solid blocks, they form a breakwater. This made it necessary to build breakwaters, which fill the empty spaces with more rocks to create an equilibrium. Because experimental work is hard and models are expensive, CFD-based numerical simulations should be studied to show how well Flow 3D software can simulate the way waves behave. In this article five models has been studied to investigate the effect of stepped mound breakwater on the behavior of breaking waves with different main sea level above breakwater crest. The results show that the Flow 3D software is getting better because it can now make waves with different heights and lengths, also, the increase in steps cause an increase in dissipation of energy and an increase in wave transmission coefficient
