Improved dynamic stall prediction of wind turbine airfoils

Journal Article


Abstract

  • 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.
