An unsteady magnetohydromagnetic natural convection on the Couette flow of electrically conducting water at 4 0 C (Pr = 11.40) in a rotating system has been considered. A Finite Element Method (FEM) was employed to find the numerical solutions of the dimensionless governing coupled boundary layer partial differential equations. The primary velocity, secondary velocity and temperature of water at 4 o C as well as shear stresses and rate of heat transfer have been obtained for both ramped temperature and isothermal plates. The results are independent of the mesh (grid) size and the present numerical solutions through the Finite Element Method (FEM) are in good agreement with the existing analytical solutions by the Laplace Transform Technique (LTT). These are shown in tabular and graphical forms.

“…In recent years, the study of Couette flow in a rotating system enhances an interest to the researchers due to its applications in secular variation of earth's magnetic field, the internal rotation rate of sun, the structure of rotating magnetic stars, the planetary and solar dynamo problems, rotating hydromagnetic generators, vortex type MHD power generators and other centrifugal machines. Taking into account these facts, unsteady hydromagnetic Couette flow of a viscous incompressible electrically conducting fluid in a rotating system is investigated by Seth et al [2,3,4,5], Chandran et al [6], Hayat et al [7], Das et al [8], Jana et al [9], Guria et al [10] and Das et al [11], under various aspects of the problem.…”

Unsteady hydromagnetic Couette flow of a viscous, incompressible and electrically conducting fluid in a rotating system between two infinitely long parallel porous plates, taking Hall current into account, in the presence of a transverse magnetic field is studied numerically. Fluid flow within the channel is induced due to impulsive movement of the lower plate of the channel and fluid motion is subjected to a uniform suction and injection at upper and lower plates. Magnetic lines of force are assumed to be fixed relative to the fluid. Numerical solutions for primary and secondary velocities are obtained from the governing momentum equation by employing explicit finite difference method. The effects of various non-dimensional parameters: Hall current parameter , magnetic parameter , suction/injection parameter and time on primary and secondary velocities are presented graphically and discussed.

“…Guria et al (2009) investigated the oscillatory MHDCouette flow of electrically conducting fluid between two parallel plates in a rotating system in the presence of an inclined magnetic field. Das et al (2009) studied unsteady hydromagnetic couette flow of a viscous incompressible electrically conducting fluid in a rotating system. Understanding the phenomenon on dispersion under the combined influence of convection and diffusion is of considerable value in many fields.…”
