Abstract In this paper thermosolutal convection of unsteady rotating Jeffrey nanofluid in porous medium is considered. The mathematical form of the problem comprises of equations of continuity, motion, concentration, and energy. To solve all these equations, we used normal mode techniques. The Brownian motion and thermophoresis has important effect on the nanofluid model. Analytical expressions for both non-oscillatory and oscillatory cases is derived when boundary surfaces are free-free. The effects of rotation (Taylor number Ta), Jeffrey parameter l, solutal Rayleigh number Rs, medium porosity , nanoparticle Rayleigh number Rn, thermo nanofluid Lewis number Ln, thermosolutal Lewis number Le, modified diffusivity ratio NA, Dufour parameter NCT, and Soret parameter NTC are analysed analytically and presented graphically. Keywords: Jeffrey nanofluid, nanofluid, thermosolutal instability, rotation, porous medium |
