Abstract

The flow over an OA209 airfoil subjected to a sinusoidal pitching motion under dynamic stall conditions and equipped with an innovative Deployable Vortex Generator actuator for stall control was experimentally and numerically investigated. Pressure and PIV measurements allow a comparison to be performed between clean and controlled cases. Separation point detection and Proper Orthogonal Decomposition are included in the analysis. Along with wind tunnel testing, numerical simulations were performed by solving the Unsteady RANS equations with the ONERA elsA code. Computations are sucessfully compared to the experimental reference and bring further understanding of the Deployable Vortex Generator actuation.
