Magnetohydrodynamics Journals

Magnetohydrodynamics (MHD) is the physical-mathematical scheme that burdens the dynamics of magnetic fields in electrically conducting fluids, e.g. plasmas and liquid metals. The word magnetohydrodynamics is constituted of the words magneto- meaning magnetic, hydro- connotation water and –dynamics attributing to the movement of an object by forces. Synonyms of MHD that are less intermittently used are the terms magnetofluiddynamics and hydromagnetics. The concept of MHD is that magnetic fields can persuade currents in a moving conductive fluid, which initiate forces on the fluid, and also change the magnetic field itself. The set of equations which explains MHD are a combination of the Navier-Stokes equations of fluid dynamics and Maxwell’s equations of electromagnetism. These differential equations have to be clarified simultaneously, either analytically or numerically. Because MHD is a fluid theory, it cannot treat kinetic phenomena, i.e., those in which the continuation of discrete particles, of a non-thermal distribution of their velocities, is crucial. Prsently magnetohydrodynamics is enforced in astrophysics and geophysics, fission and fusion, metallurgy and direct energy conversion, etc. The optimal MHD equations subsist of the continuity equation, the momentum equation, Ampere’s Law in the limit of no electric field and no electron diffusivity, and a temperature evolution equation.
