We use resolvent analysis to design active control techniques for separated flows over a
NACA 0012 airfoil. Spanwise-periodic flows over the airfoil at a chord-based Reynolds …

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 …

Thermal perturbations initiated by pulsed plasmas and lasers have demonstrated
impressive control authority in various high-speed turbulent shear flows, yet questions on …

Stall cells have been observed over stalled airfoils by many researchers and there have
been extensive discussions in the literature on their formation mechanism. They have been …

The results of experiments investigating excitation of flow instability over a VR-7 airfoil at a
post-stall angle of attack of 19° are presented. The Reynolds number based on the chord …

Excitation of a low-speed turbulent mixing layer using nanosecond dielectric barrier
discharge (ns-DBD) plasma actuators is demonstrated here under various forcing …

The application of local periodic heating for control of a spatially developing shear layer
downstream of a finite-thickness splitter plate is examined by numerically solving the two …

MPROVING the performance of the rotorcrafts is of paramount importance if they are to meet
the future challenges. Eliminating or at the very least alleviating flow separation over …

Abstract Since the mid-1990's, nonequilibrium plasmas have been brought into the limelight
as an effective method of influencing flows of aeronautical interest, including shock position …

The objective of this work is to further clarify the mechanisms associated with flow control via
thermal perturbations (ie energy deposition). The response of a low-speed turbulent mixing …
