Multi-group radiation diffusion convergence in low-density foam experiments

Abstract:: We present an in-depth analysis of a Marshak radiation wave moving through an iron-oxide (Fe₂O₃) foam using a 1D multigroup diffusive radiation transport model, MDART (Multigroup Diffusion Algorithm for Radiation Transport). We consider the consequences of under-resolving the group structure and address how this could lead to incorrect conclusions in the analysis of general supersonic radiation wave experiments. We also provide an analysis of the types of experimental outcome one may incorrectly link to physical effects but are in fact due to poor simulation practice.
