Abstract

The thermal convection in a horizontal binary fluid layer saturated an anisotropic porous medium with the effectof non-uniform temperature profile is studied analytically by linear stability analysis. The generalized eigenvalues problem subjected to various boundaries conditions are solved numericallyusing Galerkin method. The effects of solute Rayleigh number, Lewis number, mechanical anisotropy and thermal anisotropy parameters corresponding tothe six basic temperature profiles on the stationary thermal convection areshown graphically. It is found that the effects of thermal anisotropic parameter, Lewis number and solute Rayleigh number are to reinforce the stability ofthe system while the effect of mechanical anisotropic parameter is toadvancethe onset of convection.
