CHARACTERIZATION AND FLOW PHYSICS OF PLASMA SYNTHETIC JET ACTUATORS [PDF]

open access: yes, 2007
Plasma synthetic jet actuators are investigated experimentally, in which the geometrical design of single dielectric barrier discharge (SDBD) plasma actuators is modified to produce zero-mass flux jets similar to those created by mechanical devices.

Comparisons of Force Measurement Methods for DBD Plasma Actuators in Quiescent Air [PDF]

open access: yes, 2009
We have performed measurements of the force induced by both single (one electrode insulated) and double (both electrodes insulated) dielectric barrier discharge plasma actuators in quiescent air.

Wind Tunnel Testing of Active Flow Control on High-Lift Common Research Model [PDF]

open access: yes
A 10%-scale high-lift version of the Common Research Model (CRM-HL) and an Active Flow Control (AFC) version of the model equipped with a simple-hinged flap (CRM-SHLAFC) were successfully tested.

Turbulence-resolving simulations of wind turbine wakes

open access: yes, 2018
Turbulence-resolving simulations of wind turbine wakes are presented using a high--order flow solver combined with both a standard and a novel dynamic implicit spectral vanishing viscosity (iSVV and dynamic iSVV) model to account for subgrid-scale (SGS ...

Sprinkler Head Revisited: Momentum, Forces, and Flows in Machian Propulsion

open access: yes, 2011
Many experimenters, starting with Ernst Mach in 1883, have reported that if a device alternately sucks in and then expels a surrounding fluid, it moves in the same direction as if it only expelled fluid. This surprising phenomenon, which we call "Machian

Sweeping Jet Actuator in a Quiescent Environment [PDF]

open access: yes
This study presents a detailed analysis of a sweeping jet (fluidic oscillator) actuator. The sweeping jet actuator promises to be a viable flow control actuator candidate due to its simple, no moving part structure and its high momentum, spatially ...
