Irreversibility and Entropy Exclusion in Collisionless Plasmas
Alexander G. Tevzadze
We examine entropy production in reduced descriptions of collisionless plasmas. Introducing a closure dependent entropy hierarchy, we show that non-conservative moment closures gen…

A conserved thermo-mechanic invariant in extended fluid description of collisionless plasmas
E. S. Uchava, A. G. Tevzadze
We investigate linear perturbations of an incompressible, weakly collisional, anisotropic plasma in the low frequency limit using an extended 16-moment fluid description that retai…

Fire-hose instability of inhomogeneous plasma flows with heat fluxes
E. S. Uchava, A. G. Tevzadze, B. M. Shergelashvili +2
We study the effects of heat flows and velocity shear on the parallel firehose instability in weakly collisional plasma flow. For this purpose we apply an anisotropic 16-moments MH…
