The characteristics of an electric arc in a turbulent gas flow are studied. A turbulence model is constructed which considers pulsations in radiation and electrodynamic quantities. An arc with longitudinal draft in a cylindrical channel is considered in which the turbulence is determined by the gas flow regime as well as volume heat liberation. Turbulence characteristics are determined by an equation describing temperature pulsation intensity. Relationships for calculating turbulent transport, temperature distribution, radiant heat transfer, radiant heat flux, and electrical conductivity are presented. The system of energy, motion, and continuity equations was solved using the finite difference method. Studies were performed for an arc with a turbulent draft of argon in a cylindrical channel. Data obtained experimentally for a twisted flow were used to verify the model. It was found that agreement between experiment and calculated data with consideration of temperature pulsations proves to be better without consideration of twisting.
