Magnetohydrodynamics (MHD; also called magneto-fluid dynamics or hydromagnetics) is the study of the magnetic properties and behaviour of electrically conducting fluids. Examples of such magnetofluids include plasmas, liquid metals, salt water, and electrolytes. The word … Meer weergeven The first recorded use of the word magnetohydrodynamics is by Hannes Alfvén in 1942: At last some remarks are made about the transfer of momentum from the Sun to the planets, … Meer weergeven The simplest form of MHD, ideal MHD, assumes that the resistive term $${\displaystyle \eta \mathbf {J} }$$ in Ohm's law is small relative to the other terms such that it can be taken to be equal to zero. This occurs in the limit of large magnetic Reynolds numbers Meer weergeven The wave modes derived using MHD plasma theory are called magnetohydrodynamic waves or MHD waves. In general there are three MHD wave modes: Meer weergeven Importance of kinetic effects Another limitation of MHD (and fluid theories in general) is that they depend on the assumption that the plasma is strongly collisional (this is the first criterion listed above), so that the time scale of collisions is shorter … Meer weergeven In MHD, motion in the fluid is described using linear combinations of the mean motions of the individual species: the current density $${\displaystyle \mathbf {J} }$$ and … Meer weergeven In many MHD systems most of the electric current is compressed into thin nearly-two-dimensional ribbons termed current sheets. These can divide the fluid into magnetic domains, inside of which the currents are relatively weak. Current sheets in the solar corona are … Meer weergeven Resistive Resistive MHD describes magnetized fluids with finite electron diffusivity (η ≠ 0).
