ABSTRACT

In the present article, we investigate the onset of thermal convection in an electrically conducting fluid-saturated porous medium, when the fluid and solid phases are not in local thermodynamic equilibrium. The porous medium is heated from below and cooled from above. The Darcy model with anisotropic permeability is used for porous medium, while two energy equations, each representing the solid and fluid phases separately, have been considered as energy equations. The linear stability theory is used to compute the critical Rayleigh number and the corresponding wavenumber for the onset of convective motion. Effects of various parameters on thermal stability has been examined.
