Abstract

In order to improve the dynamic stall characteristics of vertical axis wind turbine, an airfoil with inclined column structure that can automatically expand and contract with the change of wind turbine azimuth angle is proposed. Taking the NACA0021 airfoil as the research object, the numerical simulation method is used to analyze its influence on the dynamic aerodynamic performance of the vertical axis wind turbine. The results show that the telescopic inclined column can significantly suppress the flow separation and increase the torque of the vertical axis wind turbine within the action phase angle, and the maximum power coefficient is increased by 13.6% compared with the original airfoil. At the same time, the telescopic inclined column can make the best working point offset to low tip speed ratio to improve the stability of the VAWT during operation.

Key words
