Magnetohydrodynamic (MHD) Waves in Plasmas
مجلة كلية التربية العلمية, 2022 The model for a magnetoplasma is given by the MHD equations, so the first aim is to give a full list of MHD equations, with the criteria of their applicability for wave propagation. The validity conditions under which the MHD equations are used require the wave frequency to be, and the seven eigenvectors are obtained.

The Exact Solution of the Riemann Problem in Relativistic MHD [PDF]
, 2006 We discuss the procedure for the exact solution of the Riemann problem in special relativistic magnetohydrodynamics (MHD). We consider both initial states leading to a set of only three waves analogous to the ones in relativistic hydrodynamics, as well ...

WhiskyMHD: a new numerical code for general relativistic magnetohydrodynamics [PDF]
, 2007 The accurate modelling of astrophysical scenarios involving compact objects and magnetic fields, such as the collapse of rotating magnetized stars to black holes or the phenomenology of gamma-ray bursts, requires the solution of the Einstein equations ...

AIP Advances, 2023 Collisionless magnetic reconnection typically requires kinetic treatment that is, in general, computationally expensive compared to fluid-based models. In this study, we use the magnetohydrodynamics with an adaptively embedded particle-in-cell (MHD-AEPIC)

Plasma Relaxation and Topological Aspects in Hall Magnetohydrodynamics [PDF]
, 2012 Parker's formulation of isotopological plasma relaxation process in magnetohydrodynamics (MHD) is extended to Hall MHD. The torsion coefficient alpha in the Hall MHD Beltrami condition turns out now to be proportional to the "potential vorticity." The ...

Explosively-driven magnetohydrodynamic (MHD) generator studies [PDF]
Digest of Technical Papers. Tenth IEEE International Pulsed Power Conference, 2002 Plasma jet generators have been designed and tested which used an explosive driver and shocktube with a rectangular cross section that optimize the flow velocity and electrical conductivity. The latest in a series of designs has been tested using a reactive load to diagnose the electrical properties of the MHD generator/electromagnet combination.

Pressureless Magnetohydrodynamics System: Riemann Problem and Vanishing Magnetic Field Limit
Advances in Mathematical Physics, 2020 This paper proposes the pressureless magnetohydrodynamics (MHD) system by neglecting the effect of pressure difference in the MHD system. Firstly, the Riemann problem for the pressureless MHD system is solved with five kinds of structures of solutions ...

Magnetohydrodynamic equations (MHD) generation code
Revista de Matemática: Teoría y Aplicaciones, 2017 A program to generate codes in Fortran and C of the full magnetohydrodynamic equations is shown. The program uses the free computer algebra system software REDUCE. This software has a package called EXCALC, which is an exterior calculus program. The advantage of this program is that it can be modified to include another complex metric or spacetime. The
