Title: Discrete Ordinates Approximations to the First- and Second-Order Radiation Transport Equations

Technical Report ·
DOI:https://doi.org/10.2172/800996· OSTI ID:800996

The conventional discrete ordinates approximation to the Boltzmann transport equation can be described in a matrix form. Specifically, the within-group scattering integral can be represented by three components: a moment-to-discrete matrix, a scattering cross-section matrix and a discrete-to-moment matrix. Using and extending these entities, we derive and summarize the matrix representations of the second-order transport equations.
