The effect of wall conductance on the hydromagnetic Couette flow and heat transfer between two parallel plates in a rotating frame of reference in the presence of an applied uniform transverse magnetic field is studied. An exact solution of the goveming equations has been obtained. It is found that both the primary and the secondary velocities decrease with an increase in wall conduetance parameter...
The purpose of the present investigation is to study an unsteady magnetohydrodynamic flow of a viscous incompressible electrically conducting fluid occupying a semi-infinite region of space bounded by an infinite vertical moving plate. The flow is considered to be gray in the presence of free convection, mass transfer and radiation. An exact solution of the goveming equations is obtained by applying...
A physical interpretation of relevance to a mathematical argument is the determination of the reality of the universe by applying a radio frequency accelerator with the Sun. The exploitation of the universe deals with the controlled thermonuclear fusion reaction of the Sun at the re sonant level to produce X-ray ernission subject to an irregular fluctuation of a magnetic field in vacuum.
The effects of thermal radiation on the flow of a viscous incompressible fluid occupying a semi-infinite region of space bounded by an infinite horizontal moving hot plate in the presence of indirect natural convection by way of an induced pressure gradient, is considered. The fluid is a gray, absorbing-emitting radiation but a nonseattering medium. An exact solution is obtained for the flow by applying...
We have examined the MHD plasma behavior of a rotating environment in the presence of an inclined magnetic field with the positive direction of the axis of rotation. The interplay of a hydromagnetic force and Coriolis force exerts its influence of a dynamo mechanism with reference to the solar and terrestrial context when the Hall current is taken into account. It is stated that the electrical discharge...
The authors in compliance with investigations (Ghosh, 1997; 2001; Ghosh and Pop, 2002) prove that resonance exhibits a thermonuclear fusion reaction over the Sun in the presence of an applied inclined magnetic field when a forced oscillation is taken into account. The interstellar space is a great deal of controversy when a forced oscillation is applied to the Sun.
The Magnetohydrodynamic (MHD) plasma Couette flow in a rotating frame of reference subject to the Hall current is studied. This problem is confined to a startup process, which deals with an impulsive start of the moving plate as well as an accelerated start of the moving plate. The solution is obtained by employing the Laplace inversion method. An asymptotic behavior of the solution is analysed for...
This note adds some comments to the papers published by Ghosh (1997; 2001). It is shown that the inertial frequency becomes significant when forced oscillation is taken into account. This emerges from the backbone of a remarkable approach of designing a spacecraft subject to a controlled thermonuclear reaction.
The Hall effects on unsteady MHD plasma behaviour of a rotating environment with oscillating pressure gradient in the presence of a transverse magnetic field have been studied. The solution in a dimensionless form contains five pertinent flow parameters, viz., 'alpha'm, E, P, 'omega' and m are, respectively, the magnetic interaction parameter, the Ekman number, the magnetic Prandtl number, the inertial...
Magnetohydrodynamic fully developed mixed convection flow of a viscous incompressible electrically conducting fluid confined to a vertical channel with asymmetric heating of the wall, is studied. It has been shown that a reversed flow occurs due to asymmetric heating of the wall when the magnitude of the buoyancy parameter Gr exceeds a certain threshold value. The limiting cases of the MHD free and...
