【 摘 要 】

Ocean current energy has become an important development direction of renewable energy and has broad application prospects. At present, most of the research on the energy of the current is on the improvement of the generator structure and the design of the blade, but the design of the blade is mostly the design of the wind turbine, which fails to meet the optimal condition of ocean currents. This paper aims at the development and utilization of ocean current energy, compares the application environment of wind turbines and ocean currents, and designs a blade suitable for ocean current energy generation devices. Through CFD simulation and PROFILI selection of blade airfoiled, the curve of the Lift-to-drag ratio with the angle of attack is obtained, and other parameters of the blade are obtained by solving the Wilson method through MATLAB. Finally, the 3D modeming is carried out by SolidWorks.
