Actuators for Active Flow Control

Louis N. Cattafesta, +1 more
- 04 Jan 2011 - 
TL;DR: This review provides a framework for the discussion of actuator specifications, characteristics, selection, design, and classification for aeronautical applications and attempts to highlight the strengths and inevitable drawbacks of each and highlight potential future research directions.

Separation control with nanosecond-pulse-driven dielectric barrier discharge plasma actuators

Jesse Little, +4 more
- 28 Aug 2012 - 
TL;DR: In this article, the efficacy of dielectric barrier discharge (DBD) plasmas driven by high voltage (approximately 15 kV) repetitive nanosecond pulses approximately 100 ns FWHM) for flow separation control is investigated experimentally on an airfoil leading edge up to Re=1x106 (62 m/s).

Plasma assisted ignition and high-speed flow control: non-thermal and thermal effects

Igor Adamovich, +9 more
- 15 Jul 2009 - 
TL;DR: In this paper, the key role of non-thermal plasma chemistry in hydrocarbon ignition by uniform, repetitively pulsed, nanosecond pulse duration, low-temperature plasmas is discussed.

Characterization of a surface dielectric barrier discharge plasma sustained by repetitive nanosecond pulses

Keisuke Takashima, +3 more
- 01 Oct 2011 - 
TL;DR: In this paper, a surface dielectric barrier discharge plasma sustained by repetitive, high-voltage, nanosecond duration pulses is characterized using phase-locked schlieren images to measure the speed of the compression waves generated by the discharge and the density gradient in the wave.

The flow field in turbulent round free jets

Christopher G. Ball, +2 more
- 01 Apr 2012 - 
TL;DR: A critical review of both experimental and computational studies of round turbulent jets is provided, beginning with the work of Tollmien (1926). as discussed by the authors traces the history, major advances, and various stages that the research community went through over the past 85-odd years, from statistical analyses through to the use of conditional sampling, proper orthogonal decomposition and structural eduction methods.

On density effects and large structure in turbulent mixing layers

Garry L. Brown, +1 more
- 24 Jul 1974 - 
TL;DR: In this article, Spark shadow pictures and measurements of density fluctuations suggest that turbulent mixing and entrainment is a process of entanglement on the scale of the large structures; some statistical properties of the latter are used to obtain an estimate of entrainedment rates, and large changes of the density ratio across the mixing layer were found to have a relatively small effect on the spreading angle.

Orderly Structure in Jet Turbulence

S. C. Crow, +1 more
- 16 Aug 1971 - 
TL;DR: In this paper, the authors show that a large-scale orderly pattern may exist in the noiseproducing region of a round subsonic jet by observing the evolution of orderly flow with advancing Reynolds number.

Vortex pairing : the mechanism of turbulent mixing-layer growth at moderate Reynolds number

C. D. Winant, +1 more
- 03 Apr 1974 - 
TL;DR: A mixing layer is formed by bringing two streams of water, moving at different velocities, together in a lucite-walled channel as mentioned in this paper, where dye is injected between the two streams just before they are brought together, marking the vorticitycarrying fluid.

On spatially growing disturbances in an inviscid shear layer

A. Michalke
- 01 Nov 1965 - 
TL;DR: In this paper, the authors used the hyperbolic-tangent velocity profile of the disturbed shear layer to obtain better agreement with experimental results by means of the inviscid linearized stability theory of spatially growing disturbances.
