Nanofluid natural convection in a porous enclosure in existence of Lorentz forces is studied. Darcy and KKL models are taken in to account for porous media and nanofluid, respectively. Influences of length of inner cylinder(rin), CuO-water volume fraction(ϕ), Hartmann (Ha) and Rayleigh (Ra) numbers for porous medium are shown in results. Contour and 3D plots are depicted for Nusselt number. Results indicate that temperature gradient decrease with increase of Lorentz forces and length of square cylinder. Effect of nanoparticle on thermal conductivity is more sensible for higher values of rin and Ha.
