Group classification of the two-dimensional magnetogasdynamics equations in Lagrangian coordinates
S. V. Meleshko, E. I. Kaptsov, S. Moyo +1
The present paper is devoted to the group classification of magnetogasdynamics equations in which dependent variables in Euler coordinates depend on time and two spatial coordinate…
Generalized Fluid Models of the Braginskii Type
P. Hunana, T. Passot, E. Khomenko +7
Several generalizations of the well-known fluid model of Braginskii (Rev. of Plasma Phys., 1965) are considered. We use the Landau collisional operator and the moment method of Gra…
Godbillon-Vey Helicity and Magnetic Helicity in Magnetohydrodynamics
G. M. Webb, A. Prasad, S. C. Anco +1
The Godbillon-Vey invariant occurs in homology theory, and algebraic topology, when conditions for a co-dimension 1, foliation of a 3D manifold are satisfied. The magnetic Godbillo…
An introductory guide to fluid models with anisotropic temperatures Part 2 -- Kinetic theory, Padé approximants and Landau fluid closures
P. Hunana, A. Tenerani, G. P. Zank +7
In Part 2 of our guide to collisionless fluid models, we concentrate on Landau fluid closures. These closures were pioneered by Hammett and Perkins and allow for the rigorous incor…
An introductory guide to fluid models with anisotropic temperatures Part 1 -- CGL description and collisionless fluid hierarchy
P. Hunana, A. Tenerani, G. P. Zank +7
We present a detailed guide to advanced collisionless fluid models that incorporate kinetic effects into the fluid framework, and that are much closer to the collisionless kinetic…
New closures for more precise modeling of Landau damping in the fluid framework
P. Hunana, G. P. Zank, M. Laurenza +5
Incorporation of kinetic effects such as Landau damping into a fluid framework was pioneered by Hammett and Perkins PRL 1990, by obtaining closures of the fluid hierarchy, where th…
