Diagnostics on Steady-State Cross-Flow Arcs, II: Influence of Velocity and Current.

Abstract

The influence of parametric variations of through-flow velocity and of arc current upon the local temperature distribution (and associated cross-sectional shape) of a steady-state, 1.1 atmosphere Argon cross-flow arc have been determined experimentally. Forced convection, at constant current, exerts profound influence upon the plasma. Isotherm distributions, obtained in a horizontal plane 4.94 mm above the anode (electrode spacing = 11.2 mm), indicate the pattern changes from that corresponding to the flow about a heated, blunt body (at low speeds) to that about a heated, highly streamlined body (at high speeds). The cross-section is noncircular, with major axis in the direction of flow. (Author)
