Experimental Study Of A Flexible Body Wave Energy Generator

The development of ocean wave renewable energy is trend of the future.China has a long coastline with rich reserves of wave energy.Developing and designing more efficient wave energy conversion devices is the key to the use of wave energy.Based on the preliminary experimental results,a series of experiments were designed to study the influence factors of wave energy conversion rate and the change of tube along the way.The results show that many factors such as wave height,wave period,water depth,the size of aperture can affect the wave energy conversion rate.Among them,the most significant impact is the wave period.Although on the surface,improve the wave period will increase the relative wave height,but when the relative wave height has reached the maximum value,if you continue increasing the wave period,it will reduce the wave energy conversion rate.It is found that the wave energy conversion rate can reach the maximum when the incident wavelength is close to the length of the rubber tube.The effect of gas chamber size on the wave energy conversion is also significant.When the pore size of the gas chamber is 2.0 cm,it shows the highest wave energy conversion efficiency.The higher wave height is,the lower wave energy conversion efficiency.Raft physical models has surface wave energy capturing effect but with severe energy lost at the same time.The expansion of rubber presents a trend of gradual increase along the process.Then,we designed the raft type flexible wave energy device by the way of changing the number of silicone tube.A series of experiments were carried out.The results show that the raft structure has a very good ability to accumulate the wave energy and provide a good idea for the optimization of the device.Later,we carried out a preliminary exploration of the combination of breakwater,and show very good response to the national strategy.
