A magnetohydrodynamic drive or MHD propulsor is a method for propelling seagoing vessels using only electric and magnetic fields with no moving parts, using magnetohydrodynamics. The working principle involves electrification of the propellant (gas or water) which can then be directed by a magnetic field, pushing the vehicle in the opposite ...
Magnetohydrodynamics is a peer-reviewed physics journal published by the Institute of Physics of the University of Latvia, covering fundamental and applied problems of magnetohydrodynamics in incompressible media, including magnetic fluids.
In magnetohydrodynamics, the magnetic Reynolds number (R m) is a dimensionless quantity that estimates the relative effects of advection or induction of a magnetic field by the motion of a conducting medium to the magnetic diffusion. It is the magnetic analogue of the Reynolds number in fluid mechanics and is typically defined by:
Oregon, a ship in the Oregon Files series of books by author Clive Cussler, has a magnetohydrodynamic drive. This allows the ship to turn very sharply and brake instantly, instead of gliding for a few miles. In Valhalla Rising, Clive Cussler writes the same drive into the powering of Captain Nemo's Nautilus.
René Moreau is Professor Emeritus at Grenoble-INP, where he directed the ENSHMG from 1982 to 1987 and where he taught fluid mechanics at all levels. [1] His research has focused on the magneto-hydrodynamics (MHD) of liquid metals, including turbulence that tends to become two-dimensional in the presence of a relatively strong magnetic field, as well as various applications of MHD in ...
Hannes Olof Gösta Alfvén (Swedish:; 30 May 1908 – 2 April 1995 [1]) was a Swedish electrical engineer, plasma physicist and winner of the 1970 Nobel Prize in Physics for his work on magnetohydrodynamics (MHD).
Jeffrey P. Freidberg was head of the Nuclear Science and Engineering Department at Massachusetts Institute of Technology from 1997 to 2003. [1] [2] [3] He is currently Professor of Nuclear Science and Engineering at MIT, [4] and a collaborator at NYU's Courant Institute of Mathematical Sciences. [5]
In magnetohydrodynamics, the induction equation is a partial differential equation that relates the magnetic field and velocity of an electrically conductive fluid such as a plasma. It can be derived from Maxwell's equations and Ohm's law, and plays a major role in plasma physics and astrophysics, especially in dynamo theory.
