Gliding arc triggered microwave plasma arc at atmospheric pressure for coal gasification application

Hydrodynamic limit for an arc discharge at atmospheric pressure

In this paper we study a partially ionized plasma that corresponds to an arc discharge at atmospheric pressure. We derive an inviscid hydrodynamic/diffusion limit, characterized by two temperatures, from a system of Boltzmann type transport equations modelling that plasma problem. The original property of this system is that impact ionization is a leading order collisional process. As a consequ...

Sustained diffusive alternating current gliding arc discharge in atmospheric pressure air

Plasma Acid Production in a Gliding Arc Plasmatron

Plasma acid is an acidic solution simply produced from water and a carrier gas in an electrical discharge. These produced solutions are of high value for biological decontamination and industrial pollutant abatement applications. While several electrical discharges have been shown to produce plasma acid, the subject of this study is the gliding arc plasmatron, a rotating gliding arc discharge. ...

Temperature measurement of an atmospheric pressure arc discharge

The CN B 2 -X 2 + molecular emission spectrum is used to measure both the vibrational and rotational temperatures in atmospheric pressure arc jet discharges. The vibrational and rotational temperature effects on the synthetic diatomic molecular spectra were investigated from the v ,v = 0,0 band to the 5,5 band. The temperatures obtained from the synthetic spectra compared with the experimental ...
