WEAK NONLINEAR STABILITY ANALYSIS OF RAYLEIGH-BENARD CONVECTION IN A ROTATING NANOFLUID LAYER

摘要

In this paper, we study the effect of rotation on the thermal instability in a horizontal layer of a Newtonian nanofluid. The nanofluid layer incorporates the effect of Brownian motion along with thermophoresis. A nonlinear analysis, using a minimal representation of the truncated Fourier series analysis, involving only two terms, has been performed to find the steady-state concentration and the thermal Nusselt numbers. The behavior of the concentration and thermal Nusselt numbers is also investigated by solving the finite amplitude equations using a numerical method.
