本文提出了一种预测风力机涡轮机翼型非定常气动载荷的动态失速模型。所提出的模型基于Beddoes-Leishman（B-L）模型，并针对风力涡轮机应用进行了修改。计算了S809翼型在失速发展和深失速区振荡时的升力、阻力和俯仰力矩。对现有实验数据的验证显示总体一致性良好。
This paper presents a dynamic stall model to predict the unsteady airloads on wind turbine airfoils. The proposed model is based on the Beddoes-Leishman (B-L) model and modifications are carried out for wind turbine applications. The lift, drag, and pitch moment of the S809 airfoil oscillating in stall-development and deep-stall regimes are predicted. Validation against available experimental data shows overall good agreement.
