In this paper, flow and heat transfer of nanofluid through a converging or diverging chael with porous medium is investigated. The fluid constantly flows under the effect of magnetic field through the chael. The diverging/converging fluid motion is modeled using the momentum and energy equations. The influence of some parameters such as opening chael angle, Reynolds number and Darcy’s number when the nanofluid flows through the non-parallel plates are studied. It is seen that high Reynolds number enhances the fluid viscosity while decreases velocity. Similarly, heat transfer reduces at high Darcy’s number owing to decreased flow consequently inteal friction reduces. The obtained results in comparison with the similar studies in the literatures show satisfactory agreement.
