Abstract: Wind power is a clean renewable energy. It plays an important role in changing environmental condition and economic development. Wind turbine is a wind energy capture control. Rotating speed control of wind turbine blade is one key problem of wind power generator technology. Through analyzing the theory of centrifugal rotating speed control, this paper carried out the experiments on centrifugal rotating speed control device of small wind turbine blade, and analyzes the effects of different wind speeds on rotating angle of wind turbine blade. A method of rotating speed control has been mentioned. The experimental results and analysis have certain reference value for design and rotating speed control of wind turbine blade.

Abstract: Based on Navier-stokes equations, Weiss-Smith matrix preconditioning method is implemented within pseudo time derivative term. AUSM+-up family schemes and LU-SGS implicit iterative method were used to solve low speed flows and were compared with literature data and theoretical value. Through comparing calculation with the literature data and theoretical value, The results showed the preconditioning algorithm can be applied efficiently to the low speeds flow field, All these works built foundations for further application of chemical flows.
