The paper presents numerical simulations of the discharge and near outlet regions of the hybrid-stabilized argon-water electric arc. Calculations have been carried out for the assumption of laminar and turbulent plasma flow regimes respectively. Results of calculations for currents 300-600 A show that the influence of turbulence is weak and the maximum difference for all the monitored physical quantities is less than 10 %. Comparison with available experiments exhibits good agreement.
