In the present article, the improvement of nanofluid heat transfer inside a porous cavity by means of a non-equilibrium model in the existence of Lorentz forces has been investigated by employing control volume based finite element method. Nanofluid properties are estimated by means of Koo-Kleinstreuer-Li. The Darcy-Boussinesq approximation is utilized for the nanofluid flow. Roles of the solid-nanofluid interface heat transfer parameter Nhs, Hartmann number Ha, porosity ε, and Rayleigh number Ra were presented. Outputs demonstrate that the convective flow decreases with the rise of Nhs, but it enhances with the rise of Ra. Porosity has opposite relationship with the temperature gradient.
