A magnetohydrodynamic generator (MHD generator) is a magnetohydrodynamic converter that transforms thermal energy and kinetic energy directly into electricity. An MHD generator, like a conventional generator, relies on moving a conductor through a magnetic field to generate electric current.
Yamato 1 on display in Kobe, Japan.The first working full-scale MHD ship. 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 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.
plays an important role in dynamo (magnetic field generation) problem. The mean magnetic field plays an important role in MHD turbulence, for example it can make the turbulence anisotropic; suppress the turbulence by decreasing energy cascade etc. The earlier MHD turbulence models assumed isotropy of turbulence, while the later models have ...
CarComplaints.com was featured in a December 2014 Lifehacker article, Five Best Car Comparison Sites, [5] and also mentioned in several New York Times articles from 2013 to 2015: Ford Windstar Minivans Recalled for a Second Time, [6] Chrysler Owners Sound Off on a Power Defect [7] and Ram Dashboards Cracking.
These systems operate in a magnetic Brayton cycle, in a reverse way of the magnetocaloric refrigerators. [8] Experiments have produced only extremely inefficient working prototypes, [ 9 ] [ 10 ] [ 11 ] however, thermodynamic analysis indicate that thermomagnetic motors present high efficiency related to Carnot efficiency for small temperature ...
Magnetically coupled pumps, or magnetic drive pumps, vary from the traditional pumping style, as the motor is coupled to the pump by magnetic means rather than by a direct mechanical shaft. The pump works via a drive magnet, 'driving' the pump rotor, which is magnetically coupled to the primary shaft driven by the motor. [ 8 ]
Also, shouldn't the formula about how much energy can be extracted include a variable for the strength of the magnetic field? The MHD propulsor formula used in the real world is (thrust)= (current) X (magnetic field strength) X (the distance between the electrodes) cc24.137.78.34 21:35, 4 February 2006 (UTC)
