A comparative numerical study of hybrid-stabilized argon-water electric arc(CCP2010)
Original language description
Předneseno na konf.:Conference on Computational Physics 2010, Trondheim, 23.-26. 6 .2010,350-351:The paper presents numerical simulations of the discharge and the near outlet regions of the hybrid-stabilized argon-water electric arc. Two different numerical methods for solving the set of conservative equations for the continuity, momentum and energy have been applied. The major difference between the results using the two methods occurs in the temperature distribution in arc fringes within the dischargechamber. This fact influences the potential drop, overpressure, reabsorption of radiation and arc efficiency. For high argon mass flow rates, a transition was found from a transonic plasma flow to a supersonic one with the maximum Mach number of 1.6. Comparison with available experimental temperature and velocity profiles shows very good agreement.
