ABSTRACT
Inspired by the slight lift of bird feathers at the trailing edge under specific conditions, an adjustable bionic flap (BF) was added to a vertical-axis wind turbine (VAWT) to improve its aerodynamic performance. Numerical simulations using the SST turbulence model were conducted to examine the BF’s flow control mechanism and how its geometry affects the VAWT’s power coefficient. The results show that the BF can evidently improve the power coefficients of the VAWT. Compared with the original VAWT, the power coefficient of the VAWT with an adjustable BF is increased by 45.2% at λ = 1.75.
