[17.16] Radiation Transport with non-isotropic Scattering by Acclerated Lambda Iteration

E. J. Lentz (U. Tenn/ORNL), A. Mezzacappa (ORNL/U. Tenn)

In standard stellar atmospheres problems the scattering of photons is taken to be isotropic. For some radiative processes, scattering is highly directional, and when these processes dominate, this must be taken into account. This is the case in neutrino radiation hydrodynamics in core collapse supernovae. We show how to adapt the ALI method for use with non-isotropic scattering and present several examples related to the core collapse supernova problem.

This work was performed under the auspices of the TeraScale Supernova Initiative, funded by SciDAC grants from the DOE Office of Science High-Energy, Nuclear, and Advanced Scientific Computing Research Programs. ORNL is managed by UT-Battelle, LLC for the U.S. Department of Energy under contract DE-AC05-00OR22725.
