The Hydrodynamics Researchon The Single Buoy Of Floating Wave Energy Conversion System

With the growing of economy, the consumption of energy is also increasing, but the fossil fuels are going to be exhausted, so lots of countries begin to develop the clean and renewable energy. At present the alternatively clean and renewable energy mainly includes wind energy, solar energy, oceanic energy. Because of its huge reserves, high feasibility and potential economic benefits, the ocean energy has become the favorite energy. With the building of construction of the ocean engineering, problems which ocean development will face come to us. For example, for the floating type wave energy power generation device that we developed, in addition to the problem of designing the structure of capturing wave energy and designing the internal system, we also need solve the problem of the interaction between wave and the wave energy generation. First of all, the problem of the wave force, there are lots of devices that cause damage without accurately analysis of the wave force. The second, the corrosion by the sea water and bio-fouling can also hinder the development of the wave energy generation, but we can improve that situation through increasing margin when we design the device. So it is the imperative thing to know the wave force.In this paper we do the following research on single type wave power device in the water.First of all, according to the different sea condition, the power of the wave energy generation is acquired, then the wave force at this power can be calculated.The second, the wave force is simulated according to the different size of buoys, different wave heights, different wave periods, based on continuous equation and N-S equation as the control equation in the iteration.The third, the accuracy of the simulation calculation is checked by comparing the experiment result and simulation data.
