MHD-RLC discharge model and the efficiency characteristics of plasma synthetic jet actuator [PDF]
, 2017 Major factors affecting efficiency of plasma synthetic jet actuator (PSJA) are analyzed based on a new discharge model in the present paper. The model couples the magnetohydrodynamics (MHD) equations with the resistor–inductor–capacitor (RLC) equations ...

Plasma actuator: Influence of dielectric surface temperature [PDF]
Experimental Thermal and Fluid Science, 2012 Plasma actuators have become the topic of interest of many researchers for the purpose of flow control. They have the advantage of manipulating the flow without the need for any moving parts, a small surface profile which does not disturb the free stream flow, and the ability to switch them on or off depending on the particular situation (active flow ...

Modeling of dielectric barrier discharge plasma actuator [PDF]
Journal of Applied Physics, 2007 Glow discharge at atmospheric pressure using a dielectric barrier discharge can induce fluid flow and operate as an actuator for flow control. In this paper, we simulate the physics of a two-dimensional asymmetric actuator operating in helium gas using a high-fidelity first-principles-based numerical modeling approach to help improve our understanding ...
