Boundary layer flow of an EyringPowell model fluid due to a stretching cylinder with variable viscosity

The present investigation consists of an analytical treatment of a steady boundary layer flow ofan eyringpowell 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 governingequations have been transformed into non-linear ordinary differential equations and are solved by apowerful 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 emergingparameters intrinsic to the problem are discussed through graphs.
