ONSET OF THERMAL CONVECTION IN A ROTATING NANOFLUID LAYER SATURATING A DARCY-BRINKMAN POROUS MEDIUM: A MORE REALISTIC MODEL
ABSTRACT
In this paper, we investigate analytically the thermal convection in a rotating nanofluid layer saturating a Darcy-Brinkman porous medium by using a more realistic linear stability analysis model. In this model, we assume that the nanoparticle concentration flux is zero on the boundaries and we can put values of temperature at the boundaries. The assumed boundary conditions neutralize the possibility of oscillatory convection, and only stationary convection occurs in the absence of rotation. But in the presence of rotation, oscillatory convection occurs due to the Coriolis effect. This paper is the extension of our previous paper in which we put both temperature and nanoparticle volume fraction at the boundaries of the nanofluid layer.
