Post-stall flow control using nanosecond pulse driven dielectric barrier discharge plasma actuators

The efficacy of thermal perturbations generated by nanosecond pulse driven dielectric barrier discharge (ns-DBD) plasma actuators for post-stall flow control is explored on a NACA 0012 airfoil. Baseline and controlled flow fields are studied using static pressure measurements, particle image velocimetry and constant temperature anemometry. Experiments are primarily performed at Re = 0.74 × 106 (U∞ = 40 m s−1) and α = 18°. Three regimes of...
