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…
