Abstract

Natural convection in an enclosure filled with a diamagnetic fluid-saturated porous medium under strong magnetic field is numerically investigated. The Brinkman-Forchheimer extended Darcy model is used to solve the momentum equations, and the energy equations for fluid and solid are solved with the Local Thermal Non-Equilibrium (LTNE) model. Computations are performed for a range of Darcy number from 10⁶ to 10^-3, Rayleigh number from 10³ to 10⁶, and magnetic force parameter γ from -200 to 0. The results show that the magnetic force has significant effect on the flow field and heat transfer in a diamagnetic fluid-saturated porous medium.
