Free convection of CuO-H2O nanofluid in a curved porous enclosure using mesoscopic approach

In this research, impact of magnetic field on CuO-H2O nanofluid free convection inside a curved porous cavity is reported. Simulations have been done via Lattice Boltzmann method (LBM). KKL model is applied to consider Brownian motion impact on nanofluid properties. Impacts of Rayleigh number (Ra), Darcy number (Da), nanofluid volume fraction (ϕ), Hartmann number (Ha) 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.
