What is the use of MHD?

MHD molten metal pump is important replacement to conventional pumps because their moving parts cannot stand the molten metal temperature. MHD molten salt pump is used for nuclear reactor coolants due to its no-moving-parts feature. Nanofluid MHD pumping is a promising technology especially for bioapplications.

What is MHD fluid?

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.

What is the working of MHD generator?

The working principle of MHD generator is based on Faraday’s Law. It states that when a conductor is moved in a magnetic field an EMF is induced in the conductor. In an MHD system, hot gases act as the conductor.

How does a MHD generator work?

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. The mechanical dynamo, in contrast, uses the motion of mechanical devices to accomplish this.

What are MHD generators explain its principle and working?

The principal of MHD power generation is very simple and is based on Faraday’s law of electromagnetic induction, which states that when a conductor and a magnetic field moves relative to each other, then voltage is induced in the conductor, which results in flow of current across the terminals.

What are the important factors when selecting materials for an MHD generator?

Requirements for material in MHD generator:  Electrodes: For high conductivity, high temperature is required. Electrically conductive and structurally stable at high temperature…. There are several types of ionization.

• Thermal Ionization.
• Magnetically induced ionization.
• Radio frequency wave induced ionisation.

What is magnetohydrodynamics What does it describe how is it derived?

The word “magnetohydrodynamics” is derived from magneto- meaning magnetic field, hydro- meaning water, and dynamics meaning movement. The set of equations that describe MHD are a combination of the Navier–Stokes equations of fluid dynamics and Maxwell’s equations of electromagnetism.

What is the main advantage of MHD power?

Advantages of MHD Generation A high conversion efficiency of around 50\%. A large amount of power is generated. Better utilisation of fuel. Since it has no moving parts, so it is more reliable.
