Triple diffusive convection of a non-Newtonian fluid under the combined effect of compressibility and variable gravity

Aggarwal A. K., Dixit D.

International Journal of Applied Mechanics and Engineering

2019

Vol. 24, no. 4

1--11

In this paper, triple diffusive convection in a Rivlin-Ericksen fluid layer, which is permeated with suspended particles in the porous medium under the effect of compressibility and variable gravity, is investigated. Linear stability theory and normal mode analysis have been used to study the problem under consideration. It is observed that, for stationary convection, suspended particles, compressibility and medium permeability have destabilizing/stabilizing effects under certain conditions. The variable gravity parameter destabilizes the system whereas stable solute gradients have a stabilizing effect.

Effect of suspended particles on thermosolutal convection of Rivlin-Ericksen fluid in porous medium with variable gravity

Aggarwal A. K., Dixit D.

International Journal of Applied Mechanics and Engineering

2018

Vol. 23, no. 3

813--820

The thermosolutal stability of a layer of the Rivlin-Ericksen fluid in a porous medium is considered under varying gravity conditions. It is found that for stationary convection, medium permeability and suspended particles have a destabilizing/stabilizing effect when gravity increases/decreases. The stable solute gradient has a stabilizing effect on the system.

Variable gravity effects on thermal instability of nanofluid in anisotropic porous medium

Chand R., Rana G. C., Kumar S.

International Journal of Applied Mechanics and Engineering

2013

Vol. 18, no. 3

631--642

In this paper, we study the effects of variable gravity on thermal instability in a horizontal layer of a nanofluid in an anisotropic porous medium. Darcy model been used for the porous medium. Also, it incorporates the effect of Brownian motion along with thermophoresis. The normal mode technique is used to find the confinement between two free boundaries. The expression of the Rayleigh number has been derived, and the effects of variable gravity and anisotropic parameters on the Rayleigh number have been presented graphically.
