Ocean Wave Energy Generation System Of Flexible Capsule Model Tests And Numerical Calculation

The development of ocean wave renewable energy is trend of the future.China has a long coastline with rich reserves of wave energy.Develop and design more efficient wave energy conversion devices is the key to the use of wave energy.Based on the mechanism of pulse fluctuation,this paper designed and producted a variety of flexible structure wave energy power generation device models with flexible silicone material,compared the effect of different forms and chosed the best one to conduct monomer physical model tests and raft physical model tests.This paper presents a series of physical tests of different depth and wave conditions to explore the effects of different factors on the effectiveness of the generation device.The results showed superduper wave energy capture effect that silicone tube played the role of convergence of wave energy and increasing wave energy density in the wave power system.Raft physical model has surface wave energy capturing effect but with severe energy lost at the same time.Wave height,water depth,wave period are factors that can affect the capture.In older to provide a basic research for the simulation of the motion process of water-filled flexible structures under wave action in SPH method,in this paper,the SPH method was used to simulate the movement of floating tank in two-dimensional.Through series simulation of the floating tank during movement in different wave conditions,and compared with the movement process of physical model experiment in same conditions,proved consistent with the physical model test results in the state of floating tank motion and the movement of the center point on the tank bottom,verified the effectiveness of SPH method in the simulation of storage floating structures under wave action problems.
