WebIn this article a couple stress magneto-hydrodynamic (MHD) nanofluid thin film flow over an exponential stretching sheet with joule heating and viscous dissipation is considered. … 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). This diffusivity leads to a breaking in the magnetic topology; magnetic … Meer weergeven her tedesco

WebIn this paper, a new approach to investigating the unsteady natural convection flow of viscous fluid over a moveable inclined plate with exponential heating is carried out. The mathematical modeling is based on fractional treatment of the governing equation subject to the temperature, velocity and concentration field. Innovative definitions of time fractional … Web14 sep. 2024 · This paper concerns the Cauchy problem of the n-dimensional generalized incompressible magneto-hydrodynamic (GMHD) equations with beta is an element of … Web21 apr. 2013 · In this paper we deal with weak solutions to the Maxwell-Landau-Lifshitz equations and to the Hall-Magneto-Hydrodynamic equations. First we prove that these solutions satisfy some weak-strong uniqueness property. Then we investigate the validity of energy identities. In particular we give a sufficient condition on the regularity of weak … mayfield homes
