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.

ABSTRACTNumerical models describing the plasma physics in the column and plume of a nontransferred, dc arc torch were used in conjunction with two experiments to quantify the extent of turbulence in the free plume. Numerical predictions were made by solving the governing conservation equations with suitable boundary conditions. The solutions indicate a high temperature, high velocity region starting at the anode which decays rapidly as the plume interacts with the atmosphere. The turbulent viscosity is predicted to be up to 140 times higher than the molecular viscosity at specific locations. Modeling results for the plume compare favorably with spectroscopic temperature measurements, and with the cone angles measured with holographic interferometry, which quantifies the amount of turbulence in the plume.
