摘要
依据风力机风轮结构设计理论和微型风力机的具体工况,从叶片数、叶片形状和翼型3方面对微型风力机风轮结构进行了优化,得到3种不同的风轮结构方案。结合微型风力机风轮的结构特点和实际工况,运用计算流体动力学软件(FLUENT)建立风轮的三维流场仿真模型,并验证该仿真模型的有效性。分别对3种不同的风轮结构进行气动性能分析,对比其输出转矩和输出功率,确定最优的微型风轮结构。
According to the structural design principle of wind turbine rotor under specified conditions,we optimize the structure of micro wind turbine rotor from three aspects,namely,the number of blade,the shape of blade and the airfoil of blade and three optimum structures are found. With computational fluid dynamics software,FLUENT,a three dimensional flow field simulation model is established with the structural characteristics and actual conditions of micro wind turbine. This simulation model has been verified and used to analyze the aerodynamics performance of the three different wind turbine rotors. As a result,an optimized structural is obtained with comparing the torque and out-put power of different rotors.
