Double Diffusive Convection with Cross-Diffusion Effects in Hybrid Nanoliquids in an Inclined Slot

Abstract

This novel study examines the effects of cross-diffusion, and nanoparticles on a hybrid nanoliquid undergoing double-diffusive convection in an inclined slot. The hybrid nanoliquid considered is unique and it contains a mixture of base liquid to which nanoparticles are suspended. The thermophysical properties of the hybrid nanoliquid are calculated using phenomenological laws and mixture theory. The results are compared with the case of mono nanoliquid and hybrid nanoliquid with one base liquid and two nanoparticles. In order to study the convective system, the shooting method along with Runge-Kutta 4th order method is employed, and the results are illustrated graphically. It is noticed that the solutal Rayleigh number, Soret parameter and inclination of the plates delay the onset of convection, while the Dufour parameter, diffusivity ratio, and the addition of nanoparticles advance the onset of the convection.
