【 摘 要 】

In this paper, we employ an approximate analytical method, namely optimal auxiliaryfunctions method (OAFM), to investigate a thin film flow of a fourth grade fluid dawn a long verticalcylinder. Our solutions are compared with those obtained by numerical integration. OAFM does notdepend upon large or small parameters and assures the convergence of the approximate solutions afteronly one iteration. OAFM is very efficient and effective.
