A high-order / low-order (HOLO) algorithm for preserving conservation in time-dependent low-rank transport calculations
Zhuogang Peng, Ryan G. McClarren
Dynamical low-rank (DLR) approximation methods have previously been developed for time-dependent radiation transport problems. One crucial drawback of DLR is that it does not conse…
Data-Driven Acceleration of Thermal Radiation Transfer Calculations with the Dynamic Mode Decomposition and a Sequential Singular Value Decomposition
Ryan G. McClarren, Terry S. Haut
We present a method for accelerating discrete ordinates radiative transfer calculations for radiative transfer. Our method works with nonlinear positivity fixes, in contrast to mos…
High-Energy Density Hohlraum Design Using Forward and Inverse Deep Neural Networks
Ryan G. McClarren, I. L. Tregillis, Todd J. Urbatsch +1
We present a study of using machine learning to enhance hohlraum design for opacity measurement experiments. For opacity experiments we desire a hohlraum that, when its interior wa…
Frequency-Dependent Material Motion Benchmarks for Radiative Transfer
Ryan G. McClarren, N. A. Gentile
We present a general solution for the radiation intensity in front of a purely absorbing slab moving toward an observer at constant speed and with a constant temperature. The solut…
