Thermal instability in a horizontal layer of Rivlin-Ericksen elastico-viscous nanofluid in porous medium is considered for more realistic boundary conditions. A linear stability analysis based upon perturbation method and normal mode technique is used to find solution of the fluid layer. The onset criterion for stationary convection is derived analytically to study the stability characteristics. The effects of the Lewis number, modified diffusivity ration, nanoparticle Rayleigh number and porosity parameter on the stability of the system are investigated analytically.
