Abstract

This paper presents the numerical simulation of the turbulence effect in the nozzle region and upstream from a rotating disc anode in the hybrid-stabilized argon-water electric arc. Results of simulation for 300-600 A and argon mass flow rates of 22.5-40 sL/min based on a space averaging definition indicate quasi-laminar flow.
