A magnetohydrodynamic drive or MHD accelerator is a method for propelling vehicles using only electric and magnetic fields with no moving parts, accelerating an electrically conductive propellant (liquid or gas) with magnetohydrodynamics.

In plasma guns where the snowplow model does not apply, a complete set of magnetohydrodynamic (MHD) equations often has to be solved numerically. As an alternative to these approaches, this dissertation explores an underutilized concept that is based on an MHD extension of the Rankine-Hugoniot model from combustion theory.

In physics and engineering, magnetohydrodynamics (MHD; also called magneto-fluid dynamics or hydro­magnetics) is a model of electrically conducting fluids that treats all interpenetrating particle species together as a single continuous medium.

Recent research has revived interest in electromagnetic railguns. A railgun utilizes the Lorentz force to accelerate an electrically conducting armature, which in turn accelerates a projectile. Our investigation identified the critical parameter that will lead to limits on railgun operation.

2011年6月27日 · This paper presents a gun-type liquid metal MHD pulse generator concept and performance analysis. This generator is composed of gun, LM-projectile, MHD power generation channel, magnet and power output system.

Magnetohydrodynamics (MHD) is the study of electrically conducting fluids. Models in which plasma is treated as a perfectly conducting fluid (ideal MHD) are the most successful models for describing the equilibrium and large-scale stability properties of magnetized plasmas.

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.
