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 Ha, Darcy number Da and Reynolds number Re on nanofluid treatment were depicted. Al 2 O 3 -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 Da and Re. Convective heat transfer reduces with rise of Hartmann number while it improves with rise of Darcy number.
