What does MHD mean?

1.1.1 Definition Magnetohydrodynamic (MHD) (magnetofluid dynamics or hydromagnetics) is the study of the dynamics of electrically conducting fluids. Examples of such fluids include plasmas, liquid metals, and salt water or electrolytes.

Who discovered magnetohydrodynamics?

waves
The discovery of magnetohydrodynamic waves was a major breakthrough in plasma physics and its applications to space physics and fusion research. The waves were discovered by Hannes Alfvén and are therefore also called Alfvén Waves.

What is MHD on a Smart car?

MHD is Smart-talk for a stop/start system and stands for Micro Hybrid Drive.

What is MHD monitor?

MHD Monitor License (unlocks the ability to data log and view up to 8 fully adjustable live gauges): Monitor your engine behavior to make sure it is running perfectly using a configurable and very responsive gauge layout with up to 8 fully adjustable gauges.

What is magnetohydrodynamic effect MRI?

Blood flow in high static magnetic fields induces elevated voltages that contaminate the ECG signal which is recorded simultaneously during MRI scans for synchronization purposes. This is known as the magnetohydrodynamic (MHD) effect, it increases the amplitude of the T wave, thus hindering correct R peak detection.

Which type of gas is used in MHD generator?

An MHD generator, like a conventional generator, relies on moving a conductor through a magnetic field to generate electric current. The MHD generator uses hot conductive ionized gas (a plasma) as the moving conductor.

What is MHD approximation?

1.1.1. The MHD approximation. The equations of magnetohydrodynamics are a reduction of the equations of fluid me- chanics coupled with Maxwell’s equations. Compared with plasma physics in general, MHD is a strongly reduced theory.

What are MHD equation?

A self-consistent set of MHD equations connects the plasma mass density ρ, the plasma velocity V, the thermodynamic (also called gas or kinetic) pressure P and the magnetic field B. In strict derivation of MHD, one should neglect the motion of electrons and consider only heavy ions. also called the Euler equation.
