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 … Visa mer 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, which is … Visa mer 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 Visa mer The wave modes derived using MHD plasma theory are called magnetohydrodynamic waves or MHD waves. In general … Visa mer 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 than the … Visa mer 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 … Visa mer In many MHD systems most of the electric current is compressed into thin nearly-two-dimensional ribbons termed current sheets. These can divide … Visa mer Resistive Resistive MHD describes magnetized fluids with finite electron diffusivity (η ≠ 0). This diffusivity leads to a breaking in the magnetic topology; magnetic field lines can 'reconnect' when they collide. Usually this term is small and reconnections can … Visa mer Webb12 maj 2024 · Theory of magnetic reconnection (a) Introduction Magnetic reconnection is a fundamental process in plasmas throughout the Universe, by which magnetic field lines change their connections and magnetic energy is converted into heat, kinetic energy and fast particle energy. It lies at the core of solar flares and geomagnetic substorms.
WebbMHD shocks have been observed in a large variety of situations.
