Study On The Designing Of Large-wind-turbine Blade

Energy sources are the foundation of modern society and economics development. And with rapid development of the industry, energy industry faces tremendous pressure of global environment pollution. Those, such as improve energy configuration, utilize regenerative energy, alleviate environment pollution, improve the people's lives quality, become the concern of global energy industry. At now the wind energy is the most favorable prospect for exploitation among the energy, and the blade of wind turbine is the key part of wind turbine. In our country the design of blade of wind turbine is still in the early stage,and technology-protecting rampart greatly block the development of wind energy. On the basis of Glauert vortex design theory, This paper has finished the model of blade of wind turbine in Pro/E, then analyze the mould by Fluent, which is a famous fluid software.During the blade of wind turbine designing, the design parameters of initialization are set by data of real product and the result of calculation. After finishing design , the model of blade of wind turbine is imported into Fluent for mesh-plotting and aerodynamic analysis, and then the result of analysis is fed back to the design for modifying the initial parameters. So the more finer capability blade could be got and the use value comes true.
