THERMAL INSTABILITY IN A BRINKMAN POROUS MEDIUM SATURATED BY NANOFLUID WITH NO NANOPARTICLE FLUX ON BOUNDARIES
RÉSUMÉ
Thermal instability in a horizontal layer of nanofluid in a porous medium is investigated. Boundary conditions for nanoparticles volume fraction are taken to be zero flux. The Darcy-Brinkman model is used for the momentum equation. A linear stability analysis based on the normal mode technique is used to study the onset of instabilities of the nanofluid layer confined between two free-free boundaries. The thermal Rayleigh-Darcy number on the onset of stationary convection has been derived by using the Galerkin weighted residuals method. Oscillatory convection has been ruled out, because of the absence of opposing buoyancy forces. The influence of the Brinkman-Darcy number (10−3 − 10−1), porosity (10−3 − 10−1), Lewis number (102 − 103), modified diffusivity ratio (1 − 10), and nanoparticles Rayleigh number [(−102) − 10] on the stationary convection are investigated both analytically and graphically. It has been found that in case of stationary convection Brinkman-Darcy number, the Lewis number and modified diffusivity ratio have a stabilizing effect while the porosity has a destabilizing effect on the fluid layer.
