On the unsteady flow of two visco‐elastic fluids between two inclined porous plates

International Journal of Stochastic Analysis, Volume 5, Issue 2, Page 131-138, 1992., 1992
This study is concerned with both hydrodynamic and hydromagnetic unsteady slow flows of two immiscible visco‐elastic fluids of Rivlin‐Ericksen type between two porous parallel nonconducting plates inclined at a certain angle to the horizontal. The exact solutions for the velocity fields, skin frictions, and the interface velocity distributions are ...

Hodographic study of non‐Newtonian MHD aligned steady plane fluid flows

International Journal of Mathematics and Mathematical Sciences, Volume 13, Issue 1, Page 93-113, 1990., 1990
A study is made of non‐Newtonian HHD aligned steady plane fluid flows to find exact solutions for various flow configurations. The equations of motion have been transformed to the hodograph plane. A Legendre‐transform function is used to recast the equations in the hodograph plane in terms of this transform function.

Invariant conservative finite-difference schemes for the one-dimensional shallow water magnetohydrodynamics equations in Lagrangian coordinates [PDF]

Open Communications in Nonlinear Mathematical Physics
Invariant finite-difference schemes for the one-dimensional shallow water equations in the presence of a magnetic field for various bottom topographies are constructed. Based on the results of the group classification recently carried out by the authors,

Magnetohydrodynamic channel flow and variational principles

International Journal of Mathematics and Mathematical Sciences, Volume 10, Issue 2, Page 391-394, 1987., 1987
This paper deals with magnetohydrodynamic channel flow problems. Attention is given to a variational principle where the boundary conditions are incorporated via a suitable functional which is stationary at the solution of the given problem; the trial functions used for the approximate solution need not satisfy any of the given boundary conditions.

Global magnetofluidostatic fields (an unsolved PDE problem)

International Journal of Mathematics and Mathematical Sciences, Volume 9, Issue 1, Page 123-130, 1986., 1986
A satisfactory theory of the Global MagnetoFluidoStatic (GMFS) Fields, where symmetric and non‐symmetric configurations can be dealt with on the same footing, has not yet been developed. However the formulation of the Nowhere‐Force‐Free, Local‐Global MFS problem about a given smooth isobaric toroidal surface 𝒮0 (actually, a degenerate initial‐value ...

Combined effect of free and forced convection on MHD flow in a rotating porous channel

International Journal of Mathematics and Mathematical Sciences, Volume 5, Issue 1, Page 165-182, 1982., 1980
This paper gives a steady linear theory of the combined effect of the free and forced convection in rotating hydromagnetic viscous fluid flows in a porous channel under the action of a uniform magnetic field. The flow is governed by the Grashof number G, the Hartmann number H, the Ekman number E, and the suction Reynolds number S. The solutions for the

Instability through porous medium of two viscous superposed conducting fluids

International Journal of Mathematics and Mathematical Sciences, Volume 5, Issue 2, Page 365-375, 1982., 1980
The stability of the plane interface separating two viscous superposed conducting fluids through porous medium is studied when the whole system is immersed in a uniform horizontal magnetic field. The stability analysis is carried out for two highly viscous fluids of equal kinematic viscosities, for mathematical simplicity.

Magnetohydrodynamic cross‐field boundary layer flow

International Journal of Mathematics and Mathematical Sciences, Volume 5, Issue 2, Page 377-384, 1982., 1981
The Blasius boundary layer on a flat plate in the presence of a constant ambient magnetic field is examined. A numerical integration of the MHD boundary layer equations from the leading edge is presented showing how the asymptotic solution described by Sears is approached.

Some geometric properties of magneto‐fluid flows

International Journal of Mathematics and Mathematical Sciences, Volume 5, Issue 2, Page 385-392, 1982., 1982
By employing an anholonomic description of the governing equations, certain geometric results are obtained for a class of non‐dissipative magnetofluid flows. The stream lines are geodesics on a normal congruence of the surfaces which are the Maxwellian surfaces.

Shear flow past a flat plate in hydromagnetics

International Journal of Mathematics and Mathematical Sciences, Volume 3, Issue 3, Page 521-534, 1980., 1979
The problem of simple shear flow past a flat plate has been extended to the hydromagnetic case in which a viscous, electrically conducting, incompressible fluid flows past an electrically insulated flat plate with a magnetic field parallel to the plate. For simplicity all physical parameters are assumed constant.
