Post-Newtonian Magnetohydrodynamics
In this paper, we derive the post-Newtonian equations of the ideal magnetohydrodynamics. To do so, we use the
modern approach to post-Newtonian theory, where the harmonic gauge is used instead of the standard ...
Measurement of Plasma Resistivity in the Edge of IR-T1 Tokamak
Abstract— The Plasma resistivity has been measured in the
edge plasma of IR-T1 tokamak. To achive the edge plasma
properties ( Te and ne ) using I-V characteristics of
movable single langmuir probe. ...
The Effects of Toroidal Magnetic Field on the Vertical Structure of Hot Accretion Flows
We solved the set of two-dimensional magnetohydrodynamic (MHD) equations for optically thin black hole accretion flows incorporating the toroidal component of the magnetic field. Following global and local MHD simulations of black hole accretion...
The Effect of Self-Gravity on the Equilibrium Structure of a Non-Rotating Thick Disk
We investigate the effect of self gravity on the equilibrium structure of a thick non rotating disk around a central object by the self similar method. We introduce three dimensionless variables Csg, Ct & Ck that indicate ...
Numerical investigation of Hydro-magnetic flow of air in three different geometries of open cavity
MHD or Magnetic hydro dynamics of an open cavity with three different depths is investigated numerically
in this paper. The SIMPLE algorithm is utilized in order to solve the equations of conservation of
momentum and energy...
Dynamics of clumps embedded in a hot accretion flow with toroidal magnetic field
Dynamics of clumps within a magnetized advection-dominated accretion flow is investigated
by solving the collisionless Boltzmann equation and considering the drag force due to the
relative velocity between ...
Hydrodynamical wind in magnetized accretion flows with convection
The existence of outflow and magnetic fields in the inner region of hot
accretion flows has been confirmed by observations and numerical magnetohydrodynamic
(MHD) simulations. We present self-similar solutions for radiatively...
An r-mode in a magnetic rotating spherical layer: application to neutron stars
The combined impact of rotation and magnetic fields on oscillations of stellar fluids is still
not well known theoretically. It mixes Alfv´en and inertial waves. Neutron stars are a place
where both effects ...
Viscous-resistive ADAF with a general large-scale magnetic field
We have studied the structure of hot accretion flow bathed in a general large-scale magnetic field. We
have considered magnetic parameters βr,ϕ,z[= c2 r,ϕ,z/(2c2 s )], where c2 r,ϕ,z are the Alfvén sound speeds in ...
