Magnetohydrodynamic flow due to noncoaxial rotations of a porous disk and a fourth‐grade fluid at infinity

open access: yesMathematical Problems in Engineering, Volume 2003, Issue 2, Page 47-64, 2003., 2003
The governing equations for the unsteady flow of a uniformly conducting incompressible fourth‐grade fluid due to noncoaxial rotations of a porous disk and the fluid at infinity are constructed. The steady flow of the fourth‐grade fluid subjected to a magnetic field with suction/blowing through the disk is studied.

Finite difference solution of radiation effects on MHD unsteady free‐convection flow over vertical plate with variable surface temperature

open access: yesJournal of Applied Mathematics, Volume 2003, Issue 2, Page 65-86, 2003., 2003
An analysis is performed to study radiation effects on magnetohydrodynamic (MHD) unsteady free‐convection flow past a semi‐infinite vertical plate with variable surface temperature in the presence of transversal uniform magnetic field. The boundary layer equations are transformed into a linear algebraic system by an implicit finite‐difference method. A

On the structure of ionizing shock waves in magnetofluiddynamics

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 29, Issue 7, Page 395-415, 2002., 2002
Ionizing shock waves in magnetofluiddynamics occur when the coefficient of electrical conductivity is very small ahead of the shock and very large behind it. For planner motion of plasma, the structure of such shock waves are stated in terms of a system of four‐dimensional equations.

Radiation effect on MHD free‐convection flow of a gas at a stretching surface with a uniform free stream

open access: yesJournal of Applied Mathematics, Volume 2, Issue 2, Page 93-103, 2002., 2002
We investigate the problem of free convection heat transfer near an isothermal stretching sheet. This has been done under the simultaneous action of buoyancy, radiation, and transverse magnetic field. The governing equations are solved by the shooting method.

MHD OBLIQUE STAGNATION-POINT FLOW OF A MICROPOLAR FLUID [PDF]

open access: yes, 2011
The steady two-dimensional oblique stagnation-point flow of an electrically conducting micropolar fluid in the presence of a uniform external electromagnetic field (E0,H0) is analyzed and some physical situations are examined.

Exact solutions of steady plane flows using (r, ψ)‐coordinates

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 23, Issue 7, Page 449-475, 2000., 2000
We determine exact solutions of steady, plane viscous incompressible magnetohydrodynamic (MHD) aligned and non‐MHD fluid flows when the polar representation of the streamline patterns for these flows are of the form (θ − f(r))/g(r) = constant.

Magneto‐micropolar fluid motion: global existence of strong solutions

open access: yesAbstract and Applied Analysis, Volume 4, Issue 2, Page 109-125, 1999., 1999
By using the spectral Galerkin method, we prove a result on global existence in time of strong solutions for the motion of magneto‐micropolar fluid without assuming that the external forces decay with time. We also derive uniform in time estimates of the solution that are useful for obtaining error bounds for the approximate solutions.

Hodographic study of plane micropolar fluid flows

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 18, Issue 2, Page 357-364, 1995., 1995
Equations of steady flow of a plane micropolar fluid are transformed to the hodograph plane by means of the Legendre transform function of the streamfunction. Results are summarized in the form of a theorem, some flow problems are investigated as applications of this theorem and exact solutions and geometry of the flow are obtained in each case.
