Abstract

In this paper, we studied the effect of rotation on the thermosolutal convection in visco-elastic nanofluid in the presence of porous medium using Walters` (model B`). The system of nanofluid layer in which nanoparticle concentration on the bottom is lower than that at the top is considered. To solve the conservation equation, we used the normal mode technique and Galerkin weighted residual method. For stationary convection, the onset criterion derived analytically and experiential that visco-elastic nanofluid behaves as a regular Newtonian nanofluid. The Oscillatory convection does not exist. The effect of rotation, thermo-nanofluid Lewis number, thermosolutal Lewis number and solutal Rayleigh number analyze analytically and graphically.

Keywords
