A kinetic model for polyatomic gas with quasi-resonant collisions leading to bi-temperature relaxation processes
Thomas Borsoni, Laurent Boudin, Julien Mathiaud +1
In this article, we extend the Boltzmann framework for polyatomic gases by introducing quasi-resonant kernels, which relax resonant interactions, for which kinetic and internal ene…

An asymptotic preserving scheme for the M1model of non-local thermal transport for two-dimensional structured and unstructured meshes
Jean-Luc Feugeas, Julien Mathiaud, Luc Mieussens +1
The M1 moment model for electronic transport is commonly used to describe non-local thermal transport effects in laser-plasma simulations. In this article, we propose a new asympto…

A New Optimization Methodology for Polar Direct Drive Illuminations at the National Ignition Facility
Duncan Barlow, A. Colaïtis, D. Viala +12
A new, efficient, algorithmic approach to create illumination configurations for laser driven high energy density physics experiments is proposed. The method is applied to a polar…
