Reflections on Magnetohydrodynamics

چکیده
1 Introduction Magnetohydrodynamics (MHD) is concerned with the dynamics of fluids that are good conductors of electricity, and specifically with those effects that arise through the interaction of the motion of the fluid and any ambient magnetic field B(x, t) that may be present. Such a field is produced by electric current sources which may be either external to the fluid (in which case we may talk of an 'applied' magnetic field), or induced within the fluid itself. The induction of a current distribution j (x , t) by flow across the field B is the

Prediction of Entrance Length for Magnetohydrodynamics Channels Flow using Numerical simulation and Artificial Neural Network
This paper focuses on using the numerical finite volume method (FVM) and artificial neural network (ANN) in order to propose a correlation for computing the entrance length of laminar magnetohydrodynamics (MHD) channels flow. In the first step, for different values of the Reynolds (Re) and Hartmann (Ha) numbers (600<ReL increases.
متن کاملOn the Weakly Nonlinear Kelvin–helmholtz Instability of Tangential Discontinuities in Mhd
We derive a quadratically nonlinear equation that describes the motion of a tangential discontinuity in incompressible magnetohydrodynamics near the onset of a Kelvin–Helmholtz instability. We show that nonlinear effects enhance the instability and give a criterion for it to occur in terms of a longitudinal strain of the fluid motion along the discontinuity.
متن کاملThe exact solution of the Riemann problem in relativistic MHD with tangential magnetic fields
We have extended the procedure to find the exact solution of the Riemann problem in relativistic hydrodynamics to a particular case of relativistic magnetohydrodynamics in which the magnetic field of the initial states is tangential to the discontinuity and orthogonal to the flow velocity. The wave pattern produced after the break up of the initial discontinuity is analogous to the non–magnetic...
متن کاملDevelopment length of laminar magnetohydrodynamics pipe flows
In this article, a laminar magnetohydrodynamics (MHD) developing flow of an incompressible electrically conducting fluid subjected to an external magnetic field is considered. The aim of the study is to propose a correlation for computing the development length of the laminar MHD developing flow in a pipe. A numerical approach is considered to solve the problem. In the first step, the numerical...
