• ANALYSIS OF SORET EFFECT ON THE ONSET OF NONLINEAR DDC IN A TWO COMPONENT BOUSSINESQ FLUID SATURATED ANISOTROPIC POROUS LAYER

Abstract

The double diffusive convection (DDC) in a horizontal anisotropic porous layer saturated with a Boussinesq fluid, which is heated and salted from below in the presence of Soret coefficient is studied analytically using nonlinear theory. The generalized Darcy model is employed for the momentum equation. The nonlinear theory provides the quantification of heat and mss transports and also explains the possibility of the finite amplitude motions. The effect of mechanical anisotropy parameter, thermal anisotropy parameter, Lewis number and Soret parameter on finite amplitude motion and heat and mass transfer are shown graphically.
