Magnetohydrodynamic Generator of Pseudosound [PDF]

Acoustical Physics, 2005
The theory of a periodic flow of a conducting magnetized liquid in the presence of an ac current passing through it is described. It is shown that the flow arising under these conditions is of pseudosound character rather than sonic, as stated in some publications.

Pulsed magnetohydrodynamic generators

IEE Colloquium on Pulsed Power '96, 1996
The paper describes the general classes of magnetohydrodynamic (MHD) generator, together with work carried out by Loughborough University Pulsed Power Group in examining the feasibility of self contained (self-excited) pulsed devices. These are driven by either rocket propellant or plastic explosive and thus operate for quite different lengths of time.

Impedance of a magnetohydrodynamic generator

British Journal of Applied Physics, 1965
The electrical impedance of a magnetohydrodynamic generator energized by shock-heated argon (Mach 14) has been measured as a function of electrode area and external impedance for applied magnetic field strengths from 100 to 10 000 G. It is found that the generator impedance is independent of electrode area over the experimental range of areas (0.02-1 ...

Analysis of Magnetohydrodynamic Generator Power Generation

Journal of Propulsion and Power, 2005
The three-dimensional current and fluid flow characteristics of diagonally connected magnetohydrodynamics generators are studied by means of numerical solutions. The formulation solves the Navier-Stokes equations in conjunction with the magnetic diffusion equation and a two-equation turbulence model on a hybrid unstructured grid.

Thermoacoustic magnetohydrodynamic electrical generator

The Journal of the Acoustical Society of America, 1987
A thermoacoustic magnetohydrodynamic electrical generator includes an intrinsically irreversible thermoacoustic heat engine coupled to a magnetohydrodynamic electrical generator. The heat engine includes an electrically conductive liquid metal as the working fluid and includes two heat exchange and thermoacoustic structure assemblies which drive the ...

Transonic Flow in a Magnetohydrodynamic Generator

The Physics of Fluids, 1961
It is shown that a decelerating "tunnel' for the onedimensional flow of a conducting gas in crossed electric field can be shifted wholly into the generator region (or wholly into the motor region) of the field by using a divergent (or convergent) duct, so that it is possible in principle to have a smooth transonic deceleration in a magnetohydrodynamic ...

Magnetohydrodynamic power generation

Journal of the Institution of Electrical Engineers, 1960
Magnetohydredynamic (mhd) power generation promises to be more efficient than present methods of generation. The ideas behind mhd generation and their development leading to the experimental generators that have been built are discussed. The extent of research into the many problems that remain to be solved in order that mhd power generation may become

Optimization of a magnetohydrodynamic power generator †

International Journal of Control, 1972
The surface area of a magnetohydrodynamic power generator duct is minimized by a procedure based on the minimum principle. The optimal control and state profiles are obtained via the numerical solution of the two-point boundary value problem, using a transition matrix algorithm in terms of the influence functions.
