Abstract
Radiation and Joule heating in the electrode region of an arc heater are discussed. Radiative transport equations for a true axisymmetric geometry are used. A subsonic code is developed to numerically solve the fluid equations with strongly coupled radiation, V -qr and Joule heating j -E, representative of a high-pressure and high-current arc heater. Analytic expression for the divergence of radiative heat flux derived in a previous paper is used. Jacobians of the radiation term are derived. The Joule heating term is computed using a previously developed code. The equilibrium gas model consists of seven species. The fluxes are differenced using Van Leer flux splitting. Using this code the effects of radiative cooling on the thermodynamic parameters of the arc core are discussed.
