    The paper presents numerical simulations of the turbulence effect in the discharge and near-outlet regions of the hybrid-stabilized argon-water electric arc. Calculations were carried out for the assumption of laminar and turbulent plasma flow models, respectively. Results of simulation for currents 300-600 A on a fine numerical grid show that the influence of turbulence is weak and the maximum difference for all the monitored physical quantities is less than 2% in the discharge region and less than 6% in the near-outlet region. Comparison with experimental temperature profiles exhibits good agreement.
