Frequency-dependent Discrete Implicit Monte-Carlo Scheme for the Radiative Transfer Equation
Elad Steinberg, Shay I. Heizler
This work generalizes the discrete implicit Monte-Carlo (DIMC) method for modeling the radiative transfer equation from a gray treatment to an frequency-dependent one. The classic…
Multi-Frequency Implicit Semi-analog Monte-Carlo (ISMC) Radiative Transfer Solver in Two-Dimensions (without Teleportation)
Elad Steinberg, Shay I. Heizler
We study the multi-dimensional radiative transfer phenomena using the ISMC scheme, in both gray and multi-frequency problems. Implicit Monte-Carlo (IMC) schemes have been in use fo…
Asymptotic Approximation in Radiative Transfer Problems
Re'em Harel, Stanislav Burov, Shay I. Heizler
We study the validity of the time-dependent asymptotic approximation in radiative transfer of photons. The time-dependent asymptotic is an approximation which uses the…
The Time-Dependent Asymptotic Approximation for the Transport Equation
Re'em Harel, Stanislav Burov, Shay I. Heizler
In this study a spatio-temporal approach for the solution of the time-dependent Boltzmann (transport) equation is derived. Finding the exact solution using the Boltzmann equation f…
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…
