- •
The effects of VGs on thick wind turbine airfoils have been investigated experimentally.
- •
The results of two experiment-setups are compared and show positive effects on aerodynamic performance of thick airfoils.
- •
VGs are suggested to be installed at x>0.2c to avoid Cl decrease at small AoA.
- •
Two-row layout of VGs is very case sensitive and should be optimized when applying on real rotor blades.
