The Experiment And Numerical Study Of Wave Suppression Performance Of Multi-layer Vertical Baffle Permeable Breakwater

As the harbor enterprise to the deep development,the traditional structure type of breakwater is expensive,the construction difficulties within the port area and serious problems such as water pollution,already cannot satisfy the demand of the social and economic development,therefore,to study a kind of suitable for different water depths and different wave factors,set through flow and wave into a new type of breakwater and wave properties has important theoretical and practical significance.(1)Based on the theory of baffle type void,dike at home and abroad research results and practical application of the engineering,design a kind of multilayer baffle openwork breakwater with vertical opening,in the different water depth h,different wave period T and wave height h under different baffle spacing and the wave performance of regular wave physical model test,the results showed that: with the increase of the incident wave period,wave attenuation coefficient increases,the wave attenuation effect is better;The higher the incident wave,the higher the wave elimination coefficient and the better the wave elimination effect.Under the condition that the breakwater width along the wave propagation direction remains unchanged,the arrangement scheme of baffle spacing in front and behind is better than other schemes of baffle spacing.(2)At the same time,this article is based on STARCCM software built multi-storey vertical opening baffle openwork breakwater numerical model,was studied by numerical simulation,wave height,wave period T H,baffle spacing layout affect the performance of the openwork breakwater wave,and of the numerical simulation is verified through experimental data,the results showed that: the results of numerical simulation and experimental data,the basic based on the numerical model can be used for the openwork STARCCM breakwater wave performance research.Through the comprehensive analysis of physical model test and numerical simulation,it is found that the permeable breakwater has better wave suppression performance for the long wave,and is especially suitable for the sea area with large waves and deep water.
