The non-equilibrium Marshak wave problem in non-homogeneous media
Nitay Derei, Shmuel Balberg, Shay I. Heizler +3
We derive a family of similarity solutions to the nonlinear non-equilibrium Marshak wave problem for an inhomogeneous planar medium which is coupled to a time dependent radiation d…
Spatial distribution of local elastic moduli in nanocrystalline metals
Menahem Krief, Yinon Ashkenazy
Elastoplastic properties of nanocrystalline metals are non-uniform on the scale of the grain size, and this non-uniformity affects macroscopic quantities as, in these systems, a si…
A unified theory of the self-similar supersonic Marshak wave problem
Menahem Krief, Ryan G. McClarren
We present a systematic study of the similarity solutions for the Marshak wave problem, in the local thermodynamic equilibrium (LTE) diffusion approximation and in the supersonic r…
Piston driven shock waves in non-homogeneous planar media
Menahem Krief
In this work, we analyze in detail the problem of piston driven shock waves in planar media. Similarity solutions to the compressible hydrodynamics equations are developed, for a s…
Self-similar solutions for the non-equilibrium nonlinear supersonic Marshak wave problem
Menahem Krief, Ryan G. McClarren
Similarity solutions to the nonlinear non-equilibrium Marshak wave problem with a time dependent radiation driving source are presented. The radiation transfer model used is the gr…
An accurate reaction-diffusion limit to the spherical-symmetric Boltzmann equation
Shay I. Heizler, Menahem Krief, Michael Assaf
We resolve a long standing question regarding the suitable effective diffusion coefficient of the spherically-symmetric transport equation, which is valid at long times. To that en…
