Modeling of the Temperature Distribution in Arc Discharge Plasma Reactor

Abstract

AbstractFor pollution control the non-thermal plasma seems to be the most convenient source of energetic electrons and chemically active species. In the electrical discharges the non-thermal plasma condition at atmospheric pressure can be obtained with fast gas flow through the discharge chamber volume, like in DC glow discharge or AC gliding arc discharge. The electrons temperature and its volumetric distribution is one of the fundamental parameters that should be study if we want to obtain the non-equilibrium low temperature plasma conditions in given geometry of the plasma reactor. These conditions depend on the kind of plasma gas and its velocity, geometry of the gliding arc reactor and on parameters of the power supply system. Paper presents a simplified mathematical model of the two -electrode gliding arc reactor to determine electron temperature and its distribution. Results of calculations are useful for selection of the power supply systems parameters and their design as to ensure the non-equilibrium state of gliding arc discharge plasma. Further calculations aim at three-and multielectrode reactors and three-dimension temperature distribution.
