Contrasting dynamic stall characteristics: Airfoil behavior in VAWT kinematics versus equivalent planar motions

Key Points

• Dynamic stall characteristics in VAWT kinematics show significant differences compared to equivalent planar motions, influencing efficiency.
• Key evidence indicates that the stall behavior alters under varying aerodynamic conditions, impacting overall performance metrics.
• Observational analysis focused on comparing airfoil behavior across different motion types—including both VAWT and planar settings.
• These findings highlight the need for tailored aerodynamic designs in applications involving vertical axis wind turbines.
