Discussion

Numerical simulations reveal biomimetic flap design improves torque in vertical axis wind turbines, suggesting enhanced aerodynamic efficiency.

The introduction of a biomimetic flap significantly enhances the aerodynamic performance of vertical axis wind turbines.
Numerical simulations indicated that the flap angle exhibits the highest sensitivity on torque among various parameters.
Computational fluid dynamics revealed the flap effectively suppresses dynamic stall at low tip-speed ratios.
Interactions between the flap angle and length were found to significantly affect turbine torque optimization.

Zhang et al. (2025) studied this question.
