An analysis of steady laminar forced convection heat transfer from a moving or stationary slender cylinder to a quiescent or flowing non-Newtonian fluid has been presented. A relative velocity parameter, {gamma}, is proposed to serve as a controlling index that properly indicates the relative importance of the velocity of the slender cylinder and the velocity of the free stream. The value of this parameter lies between 0 and 1. Furthermore, the coordinates and dependent variables are transformed to yield computationally efficient numerical solution that are valid over the entire range of relative velocity parameter from the limiting case of a non-Newtonian fluid free stream flowing over a stationary cylinder ({gamma} = 0) to the other limiting case of a moving cylinder in a quiescent non-Newtonian fluid ({gamma} = 1). The effects of the relative velocity parameter, the transverse curvature parameter, the power-law viscosity index and the generalized Prandtl number on the velocity profiles, the temperature distributions and the heat transfer group are clearly illustrated.
