Flow Control of Leading Edge Separation on Airfoil Using Dbd Plasma Actuator

3D Simulation of the Effects of the Plasma Actuator on the Unsteady, Turbulent and Developing Flow within a Circular Duct

The objective of current paper is 3D simulation of turbulent, developing flow and unsteady within a circular duct in presence of the body force vector persuaded by Dielectric barrier discharge (DBD) plasma actuator inside the surface of geometry for the first time. This article aims at investigating of applying plasma actuator to control separation with special arrangement of electrodes. For th...

Flow Control over Conical Forebody with Port Pulsed Plasma Actuator

A study using plasma port single-pulsed discharge is performed on the flow control of asymmetrical vortices over slender conical forebody. The different circumferential steady and unsteady pressure distributions are measured in the wind tunnel test. At the same time, the local side force, the increment of local side force and the overall side force and moment are calculated with the circumferen...

Underwater operation of a DBD plasma jet

A plasma jet produced in water using a submerged ac excited electrode in a coaxial dielectric barrier discharge configuration was studied. Plasma jet formation was found to occur only while the source was submerged. Plasma jet operation was characterized with and without gas flow. It was found that over 60% of the discharge power was deposited into the water and did not vary appreciably with ex...

laminar flow in annular conduits

the flow of fluids in annular conduits has been studied for over sixty years, however the resulted data are very scattered. in this paper the problem is analytically solved, starting out with navier-stokes equations. a computer solution is used to determine the shape of velocity profiles, the discharge and the friction factor in a large number of concentric and eccentric annular conduits. the e...
