Abstract

The evaluation of the nanofluid heat transfer inside the enclosure is done via a theoretical approach. This study illustrates the change of Nusselt number of nanofluid inside the enclosure with porous media in the existence of a homogeny magnetic field. The change of significant factors of the magnetic field, Rayleigh number, and nanofluid characteristics (m) on thermal characteristics has been fully investigated. Obtained data indicate that increasing the Rayleigh number has changed the impacts of the magnetic field on the heat transfer and nanofluid streamline. Moreover, the heat transfer is improved by the increasing of Ra and m factors at constant Ha = 7.5. Heat transfer enhancement is achieved at a specific m factor by increasing Ra and decreasing the Hartmann number.
