本文利用开发的程序,对BEM计算模型中诱导因子的计算方法进行研究.比较分析了已有几种计算方法的优劣,在此基础上提出一种改进的计算方法,并以美国可再生能源实验室(NREL)直径为10 m水平轴风力机叶片气动试验数据为依据,验证了本文算法的准确性和优越性.
A study on induction factors of Blade Element Momentum theory is performed by using developed programs.The advantage and disadvantage of three calculation methods are compared.On the basis of the results,an improved method is presented by the authors.The validity and advantage of this method are validated by using experiment data of a horizontal axis wind turbine with 10-meter diameter obtained from National Renewable Energy Laboratory (NREL).
