HEAT-TRANSFER IN A VISCOELASTIC BOUNDARY-LAYER FLOW OVER A STRETCHINGSHEET

Viscoelastic boundary layer flow over a stretching sheet with power-la w surface temperature including frictional heating and internal heat g eneration or absorption is studied. The non-similar boundary layer equ ations are solved to obtain the important physical quantities such as the skin friction coefficient and heat transfer coefficient. It is fou nd that the magnitude of the surface velocity gradient increases and t he surface temperature gradient decreases with the non-Newtonian param eter for the case in which the difference between the source temperatu re and that of the ambient fluid remains constant.
