Fluid model of dc glow discharge with nonlocal ionization source term

Dust particle charging in DC glow discharge plasma

Dust particles charging in a stratified positive column of a low-pressure DC glow discharge was investigated theoretically. The presented model consists of (i) previously developed 1D selfconsistent model for discharge parameters on the tube axis; (ii) ambipolar approximation for radial electric potential distribution and the assumption that the electron energy distribution function in radial d...

Double Langmuir probe measurement of plasma parameters in a dc glow discharge

In this paper, plasma main characteristics such as electron mean temperature, electron number density, and oscillation frequency have been measured experimentally using the double Langmuir probe diagnostic system. In our experiment, the plasma was generated by applying the low pressure dc glow discharge in several common gases. The experimental results indicated the highest plasma density and o...

Development of a Miniaturized Ambient Glow Discharge Ionization Source and Its Application in Elemental and Molecular Analysis

The Influence of External Magnetic Field on the Radiation Emitted by Negative Glow of a Dc Glow Discharge

This work represents a first attempt to use the cylindrical coaxial magnetron discharge (CCMD), obtained in air, as a light source. The main purpose was to realize a high efficiency of conversion of electric power to visible light and to optimize the operating conditions to minimize the cost of the light source, employing a cheap gas (air) and moderate voltage in the range of several hundreds v...

Force interaction of high pressure glow discharge with fluid flow for active separation control

Radio frequency based discharges at atmospheric pressures are the focus of increased interest in aerodynamics because of the wide range of potential applications including, specifically, actuation in flows at moderate speeds. Recent literature describing promising experimental observations, especially on separation control, has spurred efforts in the development of parallel theoretical modeling...
