| Summary: | This paper deals with exact solutions for unsteady magnetohydrodynamic (MHD) flow of a Casson fluid over an
infinite vertical oscillating plate embedded in a porous medium. The analysis of heat transfer in the presence of
Newtonian heating is also considered. Some suitable non-dimensional variables are introduced. The governing
equations together with imposed conditions are transformed into dimensionless forms. Expressions for the
velocity and temperature fields are obtained using the Laplace transform. Skin-friction and Nusselt number
are also evaluated. Solution for Newtonian fluid is also reduced as a special case. The graphical results show
that velocity decreases significantly with increases of magnetic effects, but it increases when either conjugate
parameter or porosity parameter increases. The main outcomes of the present work is that fluid flow can be
controlled by the increasing the values of Prandtl number as well as by the increasing of Casson parameter. |
