Dynamic stall on wind turbine blades

, 1991
Dynamic loads must be predicted accurately in order to estimate the fatigue life of wind turbines operating in turbulent environments. Dynamic stall contributes to increased dynamic loads during normal operation of all types of horizontal-axis wind ...

Dynamic stall modeling of a wind turbine airfoil at various stall-induced vibration zones

Frontiers in Energy Research
The present work entails investigation of the unsteady aerodynamic characteristics of a wind turbine airfoil operating in four stall-induced vibration (SIV) regimes, including normal (SIV-1) and reverse (SIV-2) flow conditions. We conducted computational

Computational prediction of airfoil dynamic stall [PDF]

, 1997
The term dynamic stall refers to unsteady flow separation occurring on aerodynamic bodies, such as airfoils and wings, which execute an unsteady motion.

Dynamic stall simulation of wind turbine airfoils

, 2015
Based on the Beddoes-Leishman (B-L) semi-empirical dynamic stall model, the dynamic stall characteristics of wind turbine airfoils were studied through the analysis of attached flows, separated flows and dynamic vortices.
