Abstract

Unsteady Magnetohydrodynamic (MHD) flow of nanofluid between two infinite parallel porous plates was investigated with considering Heat transfer and Hall Effect under constant pressure gradient. In this study, Copper as nanoparticle with water as its base fluid has been considered. The governing partial differential equations subjected to appropriate boundary conditions were derived and solved semi-analytically with homotopy perturbation method (HPM). The effects of physical parameters are graphically presented for varies values such as, the nanofluid volume fraction, Hartmann number and Reynolds number on non-dimensional velocity and temperature profile are considered. The results show that, increase in nanoparticle volume fraction  increase the amount of heat transfer to the nanofluid and hence its temperature increases.
