Multi-Group Discontinuous Asymptotic Approximation in Radiative Marshak Waves Experiments
Avner P. Cohen, Shay I. Heizler
We study the propagation of radiative heat (Marshak) waves, using modified -approximation equations. In relatively optically-thin media the heat propagation is supersonic,~i.e…
Key to understanding supersonic radiative Marshak waves using simple models and advanced simulations
Avner P. Cohen, Guy Malamud, Shay I. Heizler
This article studies the propagation of supersonic radiative Marshak waves. These waves are radiation dominated, and play an important role in inertial confinement fusion and in as…
Modeling of Supersonic Radiative Marshak waves using Simple Models and Advanced Simulations
Avner P. Cohen, Shay I. Heizler
We study the problem of radiative heat (Marshak) waves using advanced approximate approaches. Supersonic radiative Marshak waves that are propagating into a material are radiation…
The Discontinuous Asymptotic Telegrapher's Equation () Approximation
Avner P. Cohen, Roy Perry, Shay I. Heizler
Modeling the propagation of radiative heat-waves in optically thick material using a diffusive approximation is a well-known problem. In optically thin material, classic methods, s…
