The boundary layer theory had been presented in 1904 by Prandtl . The problem of boundary layer flow and heat transfer over a moving or stretching surface is of interest in numerous industrial applications such as polymer extrusion processes where the object enters the fluid for cooling below a certain temperature, hot rolling, paper production, wire drawing, aerodynamic extrusion of plastic sheets, the boundary layer along a liquid film and condensation process of metallic plate in a cooling bath and glass. The boundary layer behaviour on moving surfaces in a viscous fluid at rest is considered by Sakiadis whose work was subsequently extended. Lin and Shih considered the laminar boundary layer and heat transfer along horizontally and vertically moving cylinders with constant velocity and found that the similarity solutions could not be obtained due to the curvature effect of the cylinder.
