The kinetic theory of precipitating electrons with Maxwellian source plasma yields the well-known current-voltage relationship (CV-relationship; Knight formula), which can in most cases be accurately approximated by a reduced linear formula. Our question is whether it is possible to obtain this CV-relationship from ̄uid theory, and if so, to what extent it is physically equivalent with the more...

Starting from the kinetic formulation of the hard thermal loop effective theory, we have (re)derived the collision terms for soft modes of order g2T log(1/g) by averaging the statistical fluctuations in the plasma.

We present a gyrokinetic theory for the electromagnetic waves and instabilities with frequencies much lower than ion cyclotron frequency in finite-$\beta$ anisotropic uniform plasmas. Here, $\beta$ is ratio between plasma magnetic pressures. Kinetic effects due to both finite Larmor radii wave-particle resonances are fully kept analysis. Corresponding linear dispersion relation wave polarizatio...

Different variants of hybrid kinetic-fluid models are considered for describing the interaction of a bulk fluid plasma obeying magnetohydrodynamics (MHD) and an energetic component obeying a kinetic theory. Upon using the Vlasov kinetic theory for energetic particles, two planar Vlasov-MHD models are compared in terms of their stability properties. This is made possible by the Hamiltonian struc...

ABSTRACT In this work, the dry reforming of methane was studied using a corona and glow discharge plasma microreactors. A chemical kinetic model was developed to understand the reaction better. The modelization allowed prediction of the reactants conversion according to the energy transfer to the gas (P×τ). The β value is trait of the energy cost, whatever this value was leeser indicated ...

Second harmonics have been observed in various magnetospheric waves. Although particle simulations are able to produce the similar features as reported satellite observations, exact physical mechanism for generation of second remains uncovered yet. In this letter, we first give wave equations describing fundamental and via multiscale analysis. Then, apply a kinetic theory approach obtain conduc...
