[1] Dynamics of lightning channel corona sheath surrounding thin channel core is examined on the basis of three transmission-line-type models of the return stroke that specify different attenuation of longitudinal current with height. The corona sheath conductivity is estimated using measured radial electric field in the immediate vicinity of the lightning channel and measured channel base curr...

Previous studies have shown that electric field in the form of corona wind can be used for gas pumping. It has also been shown that the maximal volume flow rate can be achieved by an optimal design and arrangement of electrodes involved. An earlier study has shown an electrohydrodynamic (EHD) gas pump with three configurations (4, 12, and 28 emitting electrodes) can produce air flows with a max...

General relativistic numerical simulations of magnetized accretion flows around black holes show accreting gas with chaotic motions at equatorial latitudes and coronae and outflows with chaotic magnetic field at higher latitudes. However, the same simulations also produce highly relativistic, Poynting-dominated jets that are nearly consistent with the stationary paraboloidal Blandford-Znajek mo...

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 better...

Due to Venus not having a substantial planetary magnetic field the fast-flowing solar wind plasma can propagate regions close planet. Therefore, thermal atomic oxygen in thermosphere, hot corona, and resulting pickup ions are essential for determining overall interaction of planet with ambient wind. To investigate this complex system, we have initiated project where combination Thermosphere Gen...

Context. We present the first-ever simulations of non-ideal magnetohydrodynamical (MHD) stellar magnetospheric winds coupled with discdriven jets where the resistive and viscous accretion disc is self-consistently described. Aims. These innovative MHD simulations are devoted to the study of the interplay between a stellar wind (having different ejection mass rates) and an MHD disc-driven jet em...

Comprehensive study of the impulse corona characteristics is helpful to understand the transient process and guarantee a suitable insulation design of power transmission systems. In this paper, first the attenuation and deformation characteristics of lightning overvoltage traveling along a 500 kV experimental transmission line are tested. Then the lightning impulse corona characteristics on dif...

Let G1,G2 be two connected graphs. Denote the corona and the edge corona of G1, G2 by G1 ◦ G2 and G = G1 G2, respectively. In this paper, we compute the Laplacian spectrum of the corona G◦H of two arbitrary graphs G and H and the edge corona of a connected regular graph G1 and an arbitrary graph G2.
