(2022-10-06)This work presents a parametric, non-intrusive, data-driven reduced-order model (ROM) for parametric multigroup radiation transport. Full-order models (FOMs) for radiation transport are often costly in terms of computational ...
-
(2016-07-27)We present a new family of discrete-ordinates (Sn) angular quadratures based on discontinuous finite elements (DFEM) in angle. The angular domain is divided into spherical quadrilaterals (SQs) on the unit sphere surface. ...

(2022-05-25)This work explores the application of data-driven, projection-based, reduced-order models (ROMs) to parametric steady-state, neutral particle, no-fission, source-driven radiation transport. In the offline phase, ROM basis ...

(2016-05-24)The study of thermal radiative transfer in the high energy density regime is important to the National Nuclear Security Administration, and experiments are an important component of such studies. Strong non-linear coupling ...

(2016-12-02)The thermal radiative transfer equations are extremely complex to solve; however, accurate solutions are necessary for problems concerning inertial confinement fusion and radiation hydrodynamics (e.g. supernova explosions). ...
