The optimization of a magnetohydrodynamic generating duct

British Journal of Applied Physics, 1966
The variation of cross-sectional area and of the electrical loading along the length of a magnetohydrodynamic generating duct is determined so as to obtain a given power output from the minimum-sized duct with a given pressure drop along the duct. The calculation uses a one-dimensional flow model of a perfect gas with constant specific heat.

Generally covariant relativistic anisotropic magnetohydrodynamics

Physical Review E, 1995
We derive generally covariant hydrodynamical equations for a plasma with an anisotropic pressure in the external electromagnetic field. The equations are formulated in terms of the variables defined in the local plasma rest frame, in which the electric field vanishes.

A Magnetohydrodynamic Generator for Marine Energy Harvesting

OCEANS 2018 MTS/IEEE Charleston, 2018
In this article we present an approach to the description of Magneto-hydrodynamic Marine Energy Harvesting (MHMEH) system. Preliminarly, a general discussion on the principle of operation is presented. Successively, in order to move beyond the analytical model, a 3-D MHD modeling tool and a Runge Kutta method based solver are presented and they are ...

Nonequilbrium Ionization in a Magnetohydrodynamic Generator

The Physics of Fluids, 1962
A model for nonequilibrium ionization applicable to a magnetohydrodynamic generator has been developed which predicts a large increase in the plasma conductivity, if the plasma is a partially ionized monatomic gas whose temperature is such that the equilibrium ionization is smail. Experiments designed to test the validity of this model were carried out.

Alternating Current Magnetohydrodynamic Generator

Journal of Applied Physics, 1961
The design criteria of a proposed ac magnetohydrodynamic (mhd) generator are discussed. It is found that electrical losses to the moving fluid are serious unless the duct length-to-width ratio is greater than about 30. Two developments of such a generator are suggested.

Magnetohydrodynamic Generators and Nuclear Propulsion

ARS Journal, 1962
Some of the more advanced possibilities for using the potential high temperature and high specific power capability of the magnetohydrodynamic generator in nuclear propulsion are discussed. Radiating and nonradiating closed cycles using liquid and gas core reactors are considered.

Magnetohydrodynamic generators with nonequilibrium ionization

AIAA Journal, 1965
T earliest serious study of the possibility of utilizing nonequilibrium ionization in MHD generators was carried out by Karlowitz and Halasz at the Westinghouse Research Laboratories between 1938 and 1947. It was originally oriented to the development of a generator that could use combustion products at moderate temperatures.

PAMIR-3U magnetohydrodynamic generator results

Digest of Technical Papers. Tenth IEEE International Pulsed Power Conference, 1995
The Air Force's Phillips Laboratory has acquired a high power magnetohydrodynamic (MHD) generator for possible use with advanced weapons applications. This MHD generator is a PAMIR-3U, a modified Russian-built MHD generator that uses a modified rocket fuel to produce a DC electrical pulse of 100 MJ.

Infinite conductivity in general relativistic magnetohydrodynamics

Journal of Physics A: General Physics, 1972
It is pointed out that in general relativistic magnetohydrodynamics Ohm's law does not determine the current density Ja in the limit of infinite conductivity, but that it is determined by the electromagnetic field equation as in nonrelativistic magnetohydrodynamics.
