Abstract
An effect of dielectric barrier discharge on laminar transonic buffet at low Reynolds numbers of (0.5–0.7) × 106 was studied experimentally. Experiments were performed using high-speed schlieren imaging and PIV method. An actuator based on a dielectric barrier discharge was placed near the leading edge of the airfoil. The effect of the discharge frequency on transonic buffet was investigated. Transonic laminar buffet was found to be highly sensitive to perturbations created by low-power electrical discharge.
