Abstract

In this study, the differential transform method (DTM) was applied to steady flow over a rotating disk in porous medium with heat transfer. The governing equations can be written as a system of nonlinear ordinary differential equations. The approximate solutions of these equations were obtained in the form of series with easily computable terms. Then, Padé approximant was applied to increase the convergence radius of the series. The results obtained in this study were compared with the numerical results (fourth-order Runge-Kutta method).

Key words: Padé approximant, differential transform method, rotating disk, porous medium.
