In this article, nanofluid convective flow inside a porous enclosure is simulated by means of two temperature model. Control volume based finite element method is employed for this purpose. Nanofluid properties are estimated by means of KKL model. Darcy-Boussinesq approximation is utilized for nanofluid flow field. Lorentz forces effects are taken into consideration. Roles of solid-nanofluid interface heat transfer parameter (Nhs), Rayleigh number (Ra), porosity (a), and Hartmann number (Ha) are examined. Outputs demonstrate that lifrlmax enhance with rise of Nhs but it augments with rise of Ra. Porosity has opposite relationship with temperature gradient. (C) 2017 Elsevier Ltd. All rights reserved.
