Penetrative convection due to absorption of radiation in a magnetic nanofluid saturated porous layer

Studia Geotechnica et Mechanica, 2019
The present study investigates the onset of penetrative convection in- duced by selective absorption of radiation in a magnetic nanofluid saturated porous medium. The influence of Brownian motion, thermophoresis, and magnetophoresis on magnetic nanofluid

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.

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.

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,

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

Global Existence of Smooth Solutions to an Initial‐Boundary Value Problem of One‐Dimensional MHD–Vlasov Equations

Journal of Function Spaces, Volume 2025, Issue 1, 2025.
In this paper, the existence and uniqueness of the global smooth solution to an initial‐boundary value problem of one‐dimensional magnetohydrodynamics (MHD)–Vlasov equations are proved for large initial data. This equation is a fluid‐particle system which consists of the compressible MHD equations for the fluid coupled with the Vlasov equation 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.
