Effect of Suspended Particles on Thermosolutal Convection of Rivlin-Ericksen Fluid in Porous Medium with Variable Gravity

Abstract

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.

Triple Diffusive Convection of a Non-Newtonian Fluid Under the Combined Effect of Compressibility and Variable Gravity

“…The convection problem when the fluid layer is heated and soluted from below is studied by Veronis [2] and Nield [3]. The instability of non-Newtonian fluids has been studied by several authors [4][5][6][7][8][9][10][11][12][13][14][15] and [16,17,18,19,20,21]. There are so many problems in engineering, oceanography and limnology which can be studied by double diffusive convection.…”

Thermosolutal Stationary and Oscillatory Convection under Hall Currents of a Rivlin- Ericksen Nanofluid Confined between Horizontal Planes

“…They found that Hall currents and medium permeability accelerate the onset of thermosolutal instability while rotation and magnetic field postpone the onset of thermosolutal instability. Aggarwal [12] explored the phenomenon of thermosolutal convection within a porous medium hosting a Rivlin-Ericksen elastico-viscous dusty fluid under the influence of rotation. The results revealed that suspended particles and the permeability of the medium both had a destabilizing impact on the system.…”
