Simple Material-Motion Corrections for Thermal Radiative Transport

Abstract

The laboratory-frame, material-motion corrections due to Morel (2006) are generalized to include a term that transports the radiation angular intensity at a multiple of the material flow speed. The generalization is shown to retain the conservation and asymptotic properties of Morel’s treatment. When the flow-speed multiplier is 4/3, the new treatment can be derived from the comoving-frame radiation energy equation. Results are shown for a radiative shock problem using Implicit Monte Carlo.
