Title: Radiation Effect on Three Dimensional Flow Past a Vertical Porous Plate Through Porous Medium
Authors: Guria, M; Ghara, N; Jana, R N
Abstract: An analysis is made on the three dimensional flow past a vertical porous plate in the presence of radiation immersed in a porous medium. The solutions have been obtained for the velocity and temperature fields, shear stresses and rate of heat transfer using perturbation technique. It is found that the main flow velocity decreases with increase in radiation parameter for cooling of the plate and increases for heating of the plate. It is also found that with increase in radiation parameter, the main flow velocity increases for cooling of the plate and the reverse effect is observed for heating of the plate. The temperature distribution decreases with the increase of the radiation parameter. The shear stresses and the rate of heat transfer, which are of physical interest are presented in the form of tables.

Title: Radiation Effect on Three Dimensional MHD Flow Past a Vertical Porous Plate
Authors: Guria, M; Ghara, N; Jana, R N
Abstract: The magnetohydrodynamic flow of viscous incompressible fluid past a vertical
porous plate in the presence of radiation has been studied. Approximate solution for
velocity and temperature fields have been obtained by using perturbation technique.
It is found that main fluid velocity decreases with increase in magnetic parameter,
radiation parameter as well as suction parameter for cooling of the plate and
increases for heating of the plate. The temperature profile decreases with the
increase of radiation parameter.

Title: Radiative Heat Transfer to MHD Couette Flow with Variable Wall Temperature and General Magnetic Boundary Conditions
Authors: Ghara, N; Maji, S L; Das, S; Jana, R N
Abstract: The problem of radiative heat transfer to magnetohydrodynamic Couette flow of a
viscous incompressible electrically conducting fluid confined between infinite
parallel conducting walls with variable walls temperature has been studied. An exact
solution of the governing equations has been obtained in a closed form. It is found
that the velocity at any point decreases while the temperature at any point increases
with an increase in wall conductance. The induced magnetic field is strongly
affected by the magnetic field as well as wall conductances. Further, the critical
Eckert number for which there is no flow of heat either from walls to the fluid or
fluid to the walls has been obtained. It is found that the critical Eckert number at the
upper wall increases with an increase in either wall conductance parameter or
radiation parameter.

Title: Unsteady MHD Flow Between two Eccentric Rotating Disks
Authors: Maji, S L; Ghara, N; Jana, R N; Das, S
Abstract: The unsteady MHD flow of a viscous incompressible electrically conducting fluid
between two parallel disks, rotating with uniform angular velocity Ω about two
different axes has been studied. An exact solution of the governing equations has
been obtained by using Laplace transform. The solution for the velocity distributions
as well as shear stresses have been obtained for small times as well as for large
times. It is found that both the primary and secondary velocities increase on the left
of the axis of rotation with increase in rotation parameter K2 and the result is
reversed on the right of the axis of rotation. It is also found that with increase in
Hartman number, the primary velocity increases whereas the secondary velocity
decreases on the left of the axis of rotation, while the reversed result observed on the
right of the axis of rotation.
