Measurement of Plasma Parameters of Gliding Arc Driven by the Transverse Magnetic Field

The gliding arc can offer high energy efficiency and selectivity for chemical reactions and has been widely applied in material processing, environmental protection and other industrial areas. But the discharge properties, measurement of plasma parameters and related physical processes of the gliding arc discharge still need to further studied. In this study, the gliding arc was driven by the transverse magnetic field to produce the non-equilibrium plasma at high pressure. The parameters of the plasma at our observed point were measured by optical methods. The experimental result shows that the electron temperature is about 0.6 eV and the heavy particle temperature is approximately 2987±250K.
