Nanofluid flow and forced convection heat transfer due to Lorentz forces in a porous lid driven cubic enclosure with hot obstacle

Lattice Boltzmann Method (LBM) is utilized to simulate the magnetohydrodynamic (MHD) nanofluid forced convective heat transfer inside a porous three dimensional enclosure with hot cubic obstacle. Impact of Hartmann number H a , Darcy number D a and Reynolds number Re on nanofluid treatment were depicted. Al2O3- H 2 O nanofluid has been utilized considering single phase model. Results are demonstrated in forms of isokinetic, isotherms , streamlines, Nusselt number and velocity contours. Results show that temperature boundary layer becomes thinner with augment of D a and Re . Convective heat transfer reduces with rise of Hartmann number while it improves with rise of Darcy number.
