Double diffusive convection in a layer of Kuvshiniski viscoelastic nanofluid in a porous medium (Q2224269)

Summary: Double diffusive convection of Kuvshiniski viscoelastic nanofluid in a porous medium is studied for more realistic boundary conditions within the frame work of linear stability theory. The model used for nanofluid incorporates the effect of Brownian diffusion and thermophoresis. The flux of volume fraction of nanoparticles is taken to be zero on the isothermal boundaries. For the porous medium Brinkman-Darcy model is considered. The stability criterion for stationary convection has been derived and graphs have been plotted to study the effects of the Dufour parameter, Soret parameter, Lewis number, the modified diffusivity ratio and the concentration Rayleigh number on stationary convection.
