| Abstract: | Dynamic stall on Horizontal Axis Wind Turbines (HAWT) is caused by the rapid increase in the angle of attack due to sudden changes in wind speed and direction. In order to relate the changes in wind speed and direction with the variations in the blade-section angle of attack, an analytical model is proposed to determine the regions of the blade affected by dynamic stall. The so-called threshold radius has been identified and defined as the percentage of the blade length from the HAWT hub beyond which the probability of dynamic stall occurrence falls to zero. The model has been validated against the NREL Phase VI HAWT that was tested in the NASA Ames 24.4 m by 36.6 m wind tunnel. |
