Flow of a non-newtonian nanofluid between coaxial cylinders with variable viscosity

Abstract

In the present paper, we have focused our attention to highlight the study of a non-Newtonian nanofluid between coaxial cylinders with variable viscosity. The governing equations of the non-Newtonian fluid with variable viscosity along with energy and nanoparticles are given. The coupled nonlinear differential equations are solved analytically with the help of the homotopy analysis method (HAM). The convergence of the solution is discussed through h-curves. The physical features of pertinent parameters are discussed by plotting graphs. © 2012 Verlag der Zeitschrift für Naturforschung, Tübingen.
