Boundary layer flow of an Eyring–Powell model fluid due to a stretching cylinder with variable viscosity

Abstract

The present investigation consists of an analytical treatment of a steady boundary layer flow of an Eyring–Powell model fluid due to a stretching cylinder with temperature dependent variable viscosity. The heat transfer analysis is also taken into account. Using usual similarity transformations the governing equations have been transformed into non-linear ordinary differential equations and are solved by a powerful technique; the homotopy analysis method. Two models of variable viscosity, namely, Reynolds’ and Vogel’s are considered. The convergence is carefully checked by plotting h-curves. The emerging parameters intrinsic to the problem are discussed through graphs.
