CuO-water nanofluid flow due to magnetic field inside a porous media considering Brownian motion

Homogeneous nanofluid flow and forced convection heat transfer inside a lid driven porous cavity is investigated in presence of Lorentz forces. Brownian motion and shape factor influence on nanofluid treatment are taken into consideration. CVFEM is employed to simulate the voracity stream function formulation. Outputs are demonstrated the roles of Darcy number (Da), Hartmann number (Ha), Reynolds number (Re) and CuO-water volume fraction (phi). Results illustrate that the shapes of CuO nanoparticles can change the thermal behavior of nanofluid and greatest Nusselt number is obtained when Platelet shaped nanoparticles has been utilized. Convective heat transfer improves with augment of Darcy and Reynolds number but it reduces with rise of Hartmann number. (C) 2017 Elsevier B.V. All rights reserved.
