• SORET EFFECT ON DOUBLE DIFFUSIVE CONVECTION IN A VISCOELASTIC FLUID SATURATED ANISOTROPIC SPARSELY PACKED POROUS LAYER

Abstract

The Soret effect on the onset of double-diffusive convection in a viscoelastic fluid saturated anisotropic sparsely packed porous layer is studied using linear stability analyses. Linear theory is based on the normal mode technic.The modified Darcy law for viscoelastic fluid of the Oldroyd type model is employed for momentum equation. The onset criterion for stationary and oscillatory convection is derived analytically. The effect of Soret parameter, anisotropy parameters, Darcy-Prandlt number, and retardation retardation parameters on the stability of the system is investigated.
