摘要
如何处理水平轴风力机中的轴向诱导因子和周向诱导因子是其气动设计和性能计算的关键问题。本文针对风轮叶片气动设计与诱导因子计算较为烦琐的特点,根据动量叶素理论的Glauert方法和wilson方法,采用Visual Basic语言开发了风力机设计程序和诱导因子计算程序,并通过实例验证了程序的可行性。设计计算结果表明,该程序可快速完成风力机设计与诱导因子的计算。
How to treat the axial and circumferential factors is the key in the aerodynamic design and performance calculations for a horizontal axial wind turbine.To simplify the calculation of induced factors and primary aerodynamic design of a wind rotor's blade,the computer programs for calculating the induced factors and designing a wind rotor's blade are developed based on Software Visual Basic language by means of BEM(Blade Element Momentum) theory,especially,Glauert and wilson methods.And the feasibility of the programs is confirmed through an example.The design results show that the programs can quickly accomplish the calculation of induced factors and the aerodynamic design of a wind rotor's blade.
