Simulation And Optimization The Aerodymic Performance Of 10kW Wind Turbine Blade Airfoil

Research and development of advanced wind machine for wind turbine airfoils is currently a hot research field, Blade airfoil aerodynamic performance of the simulation and optimization will have important application value and theoretical significance. In this article, Hunan Electric Group Co., Ltd. to provide the "10kW direct drive wind turbine development " project for the study of wind turbine blades, the wind turbine blade airfoil aerodynamic performance of numerical simulation and design optimization of the use of anti-theory Reference to optimize the blade airfoil.The main contents are as follows:(1) Naiver-Stokes equations were used based on the numerical simulation method and based on the combination of viscous and inviscid vortex panel method analysis of wind turbine airfoil S809 dedicated under different angle of attack aerodynamic performance and flow field. The results will be compared with the experimental data, numerical analysis method to compare the two airfoil aerodynamic performance of wind power prediction.(2) In this section, Global Newton iterative method based on the XFOIL software anti design module (MDES). In their angle of attack, the reference wing leading edge, corner and thickness distribution was modified. And the modified airfoil surface velocity distribution of the upper and lower fairing, access to the new optimized airfoil and airfoil aerodynamic performance with the initial comparative analysis.(3) According to the design requirements for wind turbines and Glarert theory, optimize the use of MATLAB programming language Blades different radius of the best cross-section twist angle chord length distribution, and use UGNX5.0 Blades optimized parametric modeling, access to 10KW wind turbine rotor blades and the whole three-dimensional solid model.(4) Wind turbine analysis were compared by using GH-BLADED software platform optimized aerodynamic performance. The analysis shows that the design condition, the wind turbines were optimized design have better aerodynamic performance and to adapt to a wide range of wind speed.In this article, previous successful example of wind turbine blade design based on the 10kW small wind turbine blade aerodynamic performance of a numerical study, and through the optimization of the blade airfoil was good aerodynamic performance and wide speed Adapt the scope of the new comprehensive performance more excellent. After optimization of the blade to accept wind energy wind turbine blades to improve the efficiency, which can improve the competitiveness of wind energy.
