Multi-dimensional Numerical Scheme for Resistive Relativistic MHD
The paper describes a new upwind conservative numerical scheme for special relativistic resistive magnetohydrodynamics with scalar resistivity. The magnetic field is kept approximately divergence free and the divergence of the electric field consistent with the electric charge distribution via the method of Generalized Lagrange Multiplier. The hyperbolic fluxes are computed using the HLL prescr...
متن کاملNumerical Relativistic Hydrodynamics Based on the Total Variation Diminishing Scheme
This paper describes a multidimensional hydrodynamic code which can be used for studies of relativistic astrophysical flows. The code solves the special relativistic hydrodynamic equations as a hyperbolic system of conservation laws based on the total variation diminishing (TVD) scheme. It uses a new set of conserved quantities and employs an analytic formula for transformation from the conserv...
متن کاملWHAM: A WENO-based general relativistic numerical scheme I: Hydrodynamics
Active galactic nuclei, x-ray binaries, pulsars, and gamma-ray bursts are all believed to be powered by compact objects surrounded by relativistic plasma flows driving phenomena such as accretion, winds, and jets. These flows are often accurately modelled by the relativistic magnetohydrodynamics (MHD) approximation. Timedependent numerical MHD simulations have proven to be especially insightful...
متن کاملExplicit-Implicit Scheme for Relativistic Radiation Hydrodynamics
Relativistic flows appear in many high-energy astrophysical phenomena in which the magnetic field has a crucial role in dynamics. For example, magnetic fields connecting an accretion disk with a central star, or, different points of accretion disks are twisted and amplified due to the differential rotation, launching jets. Also magnetic fields play an important role in accretion disks to transp...
متن کاملEquation of State in Numerical Relativistic Hydrodynamics
Relativistic temperature of gas raises the issue of the equation of state (EoS) in relativistic hydrodynamics. We study the EoS for numerical relativistic hydrodynamics, and propose a new EoS that is simple and yet approximates very closely the EoS of the single-component perfect gas in relativistic regime. We also discuss the calculation of primitive variables from conservative ones for the Eo...
