Magnetohydrodynamic nanofluid convective flow in a porous enclosure by means of LBM

In this research, influence of Lorentz forces on nanofluid free convection inside a porous cavity is simulated. Simulations have been done via Lattice Boltzmann Method (LBM). Koo-Kleinstreuer-Li (KKL) model is applied in order to consider Brownian motion impact on nanofluid properties. Impacts of Darcy number ðDaÞ, Rayleigh number ðRaÞ, nanofluid volume fraction ð/Þ and Hartmann number ðHaÞ on heat transfer treatment are illustrated. Outputs demonstrate that temperature gradient reduces with increase of Ha while it increases with augment of permeability of porous media and buoyancy forces
