Abstract

Continuum equations governing steady, laminar, boundary-layer flow and heat transfer in a quiescent non-Newtonian, power-law fluid driven by a stretched porous surface are developed. The resulting partial differential equations are nondimensionalized and transformed into ordinary differential equations using similarity transformations for both variable power-law surface temperature and constant wall heat flux cases. The surface is assumed to be moving with a constant velocity. The transformed equations are solved numerically using a standard implicit finite-difference method. Graphical results for the tangential velocity and temperature profiles as well as tabulated results for the skin-friction coefficient and the Nusselt number for various parametric conditions are presented and discussed.
