Plasma Flaps and Plasma Slats: An Application of Weakly-Ionized Plasma Actuators

2nd AIAA Flow Control Conference, 2004
The experimental validation of an application of weakly-ionized plasma actuators for improved aerodynamic performance of multi-element wings and wings with movable control surfaces is presented. Two spanwise arrays of plasma actuators, configured to produce a wall-jet effect, were applied on the suction surface of a two-dimensional NACA 0015 wing model,

Switching Behavior of a Plasma-Fluidic Actuator

45th AIAA Aerospace Sciences Meeting and Exhibit, 2007
This work presents the plasma-fluidic actuator as a new type of flow control actuator. The device combines the best features of plasma actuators and fluidic oscillators to create an actuator that decouples the actuation frequency from the flow rate and overcomes the velocity limitations of the plasma actuator.

Research on Plasma Synthetic Jet Actuator

AIP Conference Proceedings, 2011
Circular dielectric barrier surface discharge (DBDs) actuator is a new concept of zero mass synthetic jet actuator. The characteristic of discharge and flow control effect of annular‐circular plasma synthetic jet actuator has been studied by means of of numerical simulation and experiment.

Wingtip Vortex Attenuation by Plasma Actuator

18th AIAA/3AF International Space Planes and Hypersonic Systems and Technologies Conference, 2012
of attack to the approach flow were changed. SD’s frequency was changed within the range of 0)715 Hz (which was limited by the experimental setup parameters). The alternating sinusoidal voltage frequency of 50 kHz and amplitude of 3,5 kV was applied to DBD’s electrodes.

Multiprocessor Modeling of DBD Plasma Actuator

38th Fluid Dynamics Conference and Exhibit, 2008
Based on the early developed single-processor numerical model for the dielectric barrier discharge simulation we have developed a multi-processor model. The time required for the DBD simulation is shown to be significantly less for the multiprocessor model than for the single-processor one. Based on the understanding of the physics of the DBD, operated

EFFECT OF ACTUATION PARAMETERS ON STABILIZATION OF METHANE DIFFUSIVE FLAMES USING PLASMA ACTUATORS

2015
The reduction of nitric oxides (NOx) in aircraft engines, gas turbines, or internal combustion engines is a main issue in the design of novel combustion systems. The reduction of the NOx emissions might be reached by lean combustion. However, the major issue is the stabilization of the flame under lean conditions.

Scaling Effects of an Aerodynamic Plasma Actuator

Journal of Aircraft, 2007
We present experimental results to yield insight into the scalability and control effectiveness of single-dielectricbarrier-discharge plasma actuators for leading-edge separation control on airfoils. The parameters investigated are chord Reynolds number, Mach number, leading-edge radius, actuator amplitude, and unsteady frequency.

Surface HF Plasma Actuator in Airflow

40th AIAA Plasmadynamics and Lasers Conference, 2009
The paper presents the first results on the experimental and numerical studied of the novel configuration of the HF discharge at the conical body in airflow. The effect of the three-electrode configuration is examined. The experimentally observed downstream stagnation and static pressure variation has shown significant flow modification in wide range ...
