Dynamic stall control via adaptive blowing
HF Müller-Vahl, CN Nayeri, CO Paschereit… - Renewable Energy, 2016 - Elsevier
An aerodynamic load control concept termed “adaptive blowing” was successfully tested on
a NACA 0018 airfoil model at Reynolds numbers ranging from 1.5· 10 5 to 5· 10 5. The
global objective was to eliminate lift oscillations typically encountered on wind turbine blade
sections. Depending on the jet momentum flux, steady blowing from a control slot in the
leading-edge region can be utilized to either enhance or reduce lift by suppressing or
inducing boundary layer separation respectively. Furthermore, high momentum blowing …
