基于动量叶素理论的风力机叶轮建模

Modeling of Wind Turbine Impeller Based on The Theory of Momentum Blade Element

基于动量叶素理论的风力发电机组叶轮建模与气动性能的数值仿真,考虑叶尖损失、轮毂损失,并对较高的轴向诱导因子进行修正,以保证风力机叶轮工作在非失速状态。本文使用Turbowinds T600-48型上风向风力机翼型数据和实验数据,通过对其建模仿真,得到输出功率,并与试验数据进行对比验证,从而验证了模型的正确性和实用性。

Numerical simulation of blade element momentum theory of wind turbine modeling and gas impeller based on performance, considering the tip loss, hub loss, and higher axial direction on the inducing factor is modiifed to ensure the wind turbine impeller in non stall condition. In this paper, the model is veriifed by comparing with the experimental data of T600-48 Turbowinds type of wind wing type data and experimental data. The model is correct and practical.
