Learning interpretable closures for thermal radiation transport in optically-thin media using WSINDy
Daniel Messenger, Ben Southworth, Hans Hammer +1
We introduce an equation learning framework to identify a closed set of equations for moment quantities in 1D thermal radiation transport (TRT) in optically thin media. While optic…

A Multiscale Eulerian Vlasov-Rosenbluth-Fokker-Planck Algorithm for Thermonuclear Burning Plasmas
Benjamin L. Reichelt, William T. Taitano, Brett D. Keenan +4
Accurate treatment of energetic fusion byproducts in laboratory plasmas often requires a kinetic description, owing to their large birth kinetic energy and long mean-free-paths com…

Exact local conservation of energy in fully implicit PIC algorithms
Luis Chacon, Guangye Chen
We consider the issue of strict, fully discrete \emph{local} energy conservation for a whole class of fully implicit local-charge- and global-energy-conserving particle-in-cell (PI…
