A Multi-Species Reactive-Boltzmann Formulation for Self-Consistent Kinetic Simulation of Burning Fusion Plasmas
Mark Dunn, Jingwei Hu, Uri Shumlak
Discrepancies between experimental data and radiation-hydrodynamic models of burning plasmas at the National Ignition Facility have been attributed, in part, to possible deviations…
Control of kinetic plasma instabilities by laser fields
Nicolas Crouseilles, Lukas Einkemmer, Qin Li +2
We study the possibility of controlling kinetic plasma instabilities by using lasers to apply external electromagnetic fields. We derive the dispersion relation for the correspondi…
Effects of transitional orbit magnetization on transport and current in Z pinches
D. W. Crews, E. T. Meier, U. Shumlak
The azimuthal self-magnetic field of the ideal Z pinch contains a central magnetic null. Trajectories around this null govern transport in the core. Particles follow cyclotron orbi…
Asymptotic perpendicular transport in low-beta collisionless plasma
Jack Coughlin, Jingwei Hu, Uri Shumlak
Kinetic physics, including finite Larmor radius (FLR) effects, are known to affect the physics of magnetized plasma phenomena such as the Kelvin-Helmholtz and Rayleigh-Taylor insta…
Hybridizable discontinuous Galerkin methods for solving the two-fluid plasma model
Andrew Ho, Uri Shumlak
The two-fluid plasma model has a wide range of timescales which must all be numerically resolved regardless of the timescale on which plasma dynamics occurs. The answer to solving…
The Kadomtsev pinch revisited for sheared-flow-stabilized Z-pinch modeling
Daniel W. Crews, Iman A. M. Datta, Eric T. Meier +1
The Kadomtsev pinch, namely the Z-pinch profile marginally stable to interchange modes, is revisited in light of observations from axisymmetric MHD modeling of the FuZE sheared-flo…
Phase space eigenfunctions with applications to continuum kinetic simulations
D. W. Crews, U. Shumlak
Continuum kinetic simulations are increasingly capable of resolving high-dimensional phase space with advances in computing. These capabilities can be more fully explored by using…
Robust and conservative dynamical low-rank methods for the Vlasov equation via a novel macro-micro decomposition
Jack Coughlin, Jingwei Hu, Uri Shumlak
Dynamical low-rank (DLR) approximation has gained interest in recent years as a viable solution to the curse of dimensionality in the numerical solution of kinetic equations includ…
