SORET AND DUFOUR EFFECTS ON THERMOSOLUTAL CONVECTION IN JEFFREY NANOFLUID IN THE PRESENCE OF POROUS MEDIUM

In this paper the thermosolutal instability of Jeffrey nano-fluid in a porous medium is considered. The Navier-Stokes equations of motion of the fluid are modified under the impact of the Jeffrey parameter and nanoparticles. From the linear stability analysis, based upon normal modes analysis method, the dispersion relation accounting for the effect of various parameters is derived. The effects of Jeffrey parameter lambda, solutal Rayleigh number R-S, medium porosity epsilon, nano-particle Rayleigh number R-N, thermo-nanofluid Lewis number L-n, thermosolutal Lewis number L-e, modified diffusivity ratio N-A, Dufour parameter N-CT, and Soret parameter N-TC, are analysed analytically and presented graphically
