Analysis of periodic and aperiodic convective stability of double diffusive nanofluid convection in rotating porous layer

doi:10.1007/s10483-016-2026-8

Abstract

Abstract:

The onset of periodic and aperiodic convection in a binary nanofluid satu-rated rotating porous layer is studied considering constant flux boundary conditions. The porous medium obeys Darcy's law, while the nanofluid envisages the effects of the Brow-nian motion and thermophoresis. The Rayleigh numbers for stationary and oscillatory convection are obtained in terms of various non-dimensional parameters. The effect of the involved physical parameters on the aperiodic convection is studied graphically. The results are validated in comparison with the published literature in limiting cases of the present study.

Key words: rotating porous medium, natural convection, nanofluid, thermophoretic flux
