Abstract

Abstract In this research, impact of magnetic field on CuO–H 2 O 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.
