Transport of Magnetohydrodynamic nanofluid in a porous media

- Magnetic field influence on free convection of nanofluid in porous media is studied.
- CVFEM is applied to solve this problem.
- Nuave increases with increase of ϕ and Ra.
- E increases with increase of Ha.

CuO-water nanofluid MHD convective flow in a porous cavity is studied. Darcy and KKL models are considered for porous media and nanofluid, respectively. The solutions of final equations are obtained by CVFEM. Effective parameters are major axis of elliptic cylinder, CuO-water volume fraction, eccentricity, Hartmann and Rayleigh numbers for porous medium. A correlation for Nuave is presented.Resultsdepicted that heat transfer improvement enhances with rise of buoyancy forces and major axis of elliptic cylinder. Influence of adding nanoparticle augments with augment of Lorentz forces. Increasing eccentricity and Hartmann number leads to reduce Nusselt number.
