Efficient, Nonlinear Second Moment Methods for Multigroup Thermal Radiative Transfer
Samuel Olivier, James S. Warsa, HyeongKae Park
Thermal radiative transfer (TRT) presents significant computational challenges due to the stiff, nonlinear coupling between radiation and material energy, particularly in multigrou…
Consistent Second Moment Methods with Scalable Linear Solvers for Radiation Transport
Samuel Olivier, Ben S. Southworth, James S. Warsa +1
Second Moment Methods (SMMs) are developed that are consistent with the Discontinuous Galerkin (DG) spatial discretization of the discrete ordinates (or \Sn) transport equations. T…
One-sweep moment-based semi-implicit-explicit integration for gray thermal radiation transport
Ben S. Southworth, Samuel S. Olivier, HyeongKae Park +1
Thermal radiation transport (TRT) is a time dependent, high dimensional partial integro-differential equation. In practical applications such as inertial confinement fusion, TRT is…
