Název v původním jazyce

Integrated parametric study of a hybrid-stabilized argon?water arc under subsonic, transonic and supersonic plasma flow regimes

Popis výsledku v původním jazyce

This paper presents a numerical investigation of characteristics and processes in the worldwide unique type of thermal plasma generator with combined stabilization of arc by argon flow and water vortex, the so-called hybrid-stabilized arc. The arc has been used for spraying of ceramic or metallic particles and for pyrolysis of biomass. The net emission coefficients as well as the partial characteristics methods for radiation losses from the argon?water arc are employed. Calculations for 300?600A with 22.5?40 standard litres per minute (slm) of argon reveal transition from a transonic plasma flow for 400A to a supersonic one for 600A with a maximum Mach number of 1.6 near the exit nozzle of the plasma torch. A comparison with available experimental datanear the exit nozzle shows very good agreement for the radial temperature profiles. Radial velocity profiles calculated 2mm downstream of the nozzle exit show good agreement with the profiles determined from the combination
