Supersonic jets, particularly shock-containing jets, often exhibit high-intensity, discrete-
frequency acoustic tones. These tones are the signature of an aeroacoustic resonance loop …

Turbulent jet noise is a controversial fluid mechanical puzzle that has amused and
bewildered researchers for more than half a century. Whereas numerical simulations are …

The paper reviews recent progress in two rapidly develo** engineering applications of
plasmas, plasma assisted combustion and plasma assisted high-speed flow control …

The paper discusses experimental characterization of a surface dielectric barrier discharge
plasma sustained by repetitive, high-voltage, nanosecond duration pulses. The discharge …

Bow shock perturbations in a Mach 5 air flow, produced by low-temperature, nanosecond
pulse, and surface dielectric barrier discharge (DBD), are detected by phase-locked …

Localized arc filament plasma actuators (LAFPAs) are used for shock wave/boundary layer
interaction induced separation control in a Mach 2.3 flow. The boundary layer is fully …

We perform a computational study on the effects of localized arc filament plasma actuator
based control on the flow field and acoustics of a supersonic 2: 1 aspect ratio rectangular jet …

Flow control technologies have been used in the past century to control fluid flows. This text
presents the current state of the art in emerging modern flow control technologies and …

Free shear layers are building blocks of many flows of interest in applications, including jets,
cavity flows, and separated flows. It was found several decades ago that free shear layers …

The interaction between the gas-heating phenomenon in a pulsed discharge in atmospheric-
pressure air and the separated shear layer in the flow around the airfoil is discussed. The …
