Thermal radiation effects on the flow by an exponentially stretching surface: A series solution

Abstract

This article analytically describes the thermal radiation effects on the flow and heat transfer characteristics. The flow in a second-grade fluid is created due to an exponentially porous stretching surface. The series solutions of velocity and temperature are developed by a homotopy analysis method. The heat transfer results are obtained for the two cases, namely, (i) the prescribed exponential order surface temperature (PEST) and (ii) the prescribed exponential order heat flux (PEHF). It is noticed that the temperature profile in both cases decreases when radiation parameter is increased. © 2010 Verlag der Zeitschrift für Naturforschung, Tübingen.
