Flux-limited diffusion theory with anisotropic scattering

Journal Article · · Nucl. Sci. Eng.; (United States)
OSTI ID:6714703
The Chapman-Enskog procedure of kinetic theory is used to obtain a flux-limited diffusion theory for linear transport problems. The analysis is carried out within the context of multigroup theory, with an arbitrary scattering matrix involving anisotropic effects for both within-group and group-to group scattering. Aside from the question of flux limiting, a new definition of the transport cross section arises naturally from the analysis.
