Triple diffusive convection study of a binary nanofluid saturated rotating porous layer under the influence of magnetic field

Abstract

The onset of triple diffusive linear aperiodic and periodic convection for a magnetic field exposed closely packed rotating porous layer saturated with nanofluid has been studied analytically. The boundaries are maintained at a constant flux for nanoparticle concentration. The closely packed porous layer obeys the Darcy law, while the nanofluid is under the influence of Brownian motion and thermophoresis. The expression of Rayleigh numbers’ has been obtained as function of Chandrasekhar number along with other pertinent parameters and studied graphically. Some of the convective systems already established in the literature, are shown to be special cases of the present study.
