Research Of The Flexible Breakwater System Based On Flow Reduction And Ocean Energy Capture

As a new type of renewable and clean energy,ocean energy can make contributions to the sustainable development of the world economy,and ocean resources provide the necessary guarantee for the rigid material demand and food supply.Most of existing breeding equipments gathered in harbour,and adopt the mechanized breeding,however,bay aquaculture already have tended to be saturated and In addition to some drawbacks in the structural design,the poor performance in poor water quality and environmental,the poor impact of wind and wave resistance,the existing breeding equipments also have difficulties in the supply of auxiliary equipment and other practical problems.In order to solve these problems,this paper mainly studies the following contents.Analysis of the existing actual sea condition applying to existing Ocean ecological breeding equipment,based on the physical oceanography,marine hydrodynamics,water movement characteristics theoretical and so on,focuses on researching wave and ocean current in actual ocean、tide coupling interaction,establishes an effective and accurate model of the coupling fluid.According to the practical situation of coastal ecological aquaculture areas,combined with the motion and force of energy capture impeller in the coupling of fluid and capture efficiency for different forms of impeller.,comprehensive analysis of the traditional breakwater and ocean energy capture power generation system,and put forward a new type of flexible protection system reducing wave flow,confirms that the protection system is mainly composed of floating type HDPE pipe and resistance of ocean energy capture device,and theoretical analysis of the flow dissipation and capture efficiency effect of flexible protection systems.Based on the model similarity criterion,establish the three-dimensional model of the impeller,and carry on CFD simulation.Through actual hydrodynamic test in laboratory pool,and build the corresponding tide test experiment system,by comparison and analysis of experimental results to optimize the flexible protection system.
