Analysis of energy balance of the arc discharge limited by walls

Keywords: arc discharge, heat exchange, radiation regime, channel model
Pages: 413-421


The modeling of the formation of the equilibrium arc discharge structure in the axisymmetric formulation was carried out in a wide range of the values of current and radius. The boundary separating the radiation and heat-conducting regimes of discharge combustion was determined from computed data. The influence of energy mechanisms on the structure of the discharge was analysed, and a channel model was proposed for computing its parameters in the radiation regime.
