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 +5
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…
