The Acceleration Mechanism of Resistive Mhd Jets Launched from Accretion Disks
We analyzed the results of non-linear resistive magnetohydrodynamical (MHD) simulations of jet formation to study the acceleration mechanism of axisymmetric, resistive MHD jets. The initial state is a constant angular momentum, polytropic torus threaded by weak uniform vertical magnetic fields. The time evolution of the torus is simulated by applying the CIP-MOCCT scheme extended for resistive ...
متن کاملMHD thermal radiation and chemical reaction effects with peristaltic transport of the eyring-powell fluid through a porous medium
In this paper, we analyze the thermal radiation and chemical reaction impacts on MHD peristaltic motion of the Eyring-Powell fluid through a porous medium in a channel with compliant walls under slip conditions for velocity, temperature, and concentration. Assumptions of a long wave length and low Reynolds number are considered. The modeled equations are computed by using the perturbation metho...

In order to see the occurrence of magnetic reconnection in the solar chromosphere, we investigate the behavior of non-linear perturbations on the magneto hydro dynamic (MHD) equations. Numericalstudy of the resistive tearing instability in a current sheet is presented by considering the MHD framework.To do this, the four field model is applied. It is shown based on the simulation that the non-l...
متن کاملPhysical Properties of Parasitic Modes in Non-ideal Mhd Accretion Disks
We investigate the stability of incompressible, exact, non-ideal magnetorotational (MRI) modes against parasitic instabilities for a broad range of dissipation coefficients, relevant to astrophysical and laboratory environments. This allows us to uncover the asymptotic behavior of the fastest parasites in terms of the Elsasser number, Λη, when viscous effects are not important. We calculate the...
متن کاملStudy of B-Splines finite element discretization of Physics-based Preconditioning for fluid mechanics models
The numerical simulation of large-scale MHD instabilities in confined magnetic fusion devices (called a tokamak geometry), relies on solving a Fluid model coupled with Maxwell equations. Solving these equations in the complicated geometry of the tokamak is a highly demanding task due to the strong temporal and spatial multi-scale nature of the problem and the anisotropies induced by the magneti...
