Channel-Arc Model of DC Hydrogen Arc Plasma: Influence Of Radiation and Very High Pressure

Abstract : This study focuses on a wall-stabilized hydrogen arc column at low current. The problem is solved numerically by using simplified Ohm's law and deriving the stationary Elenbaas-Heller equation from an energy balance where conduction and radiation are considered. The latter is computed using Lowke's approach of net emission coefficient where both background continuum and line spectrum are considered. This work aims to derive the electric characteristic and its sensibility to the model parameters and study the influence of a 20-bar pressure.
