Heat transfer characteristics of a continuous stretching surface

Abstract

The similarity solutions for the governing ordinary differ- ential equations of the boundary layer corresponding to a stretching surface have been reported, Power law velocity and temperature distribution were assumed for velocity exponent 3 > m > - 0.41176, - 1.1 _> m >_ - 3, and for temperature exponent 3 > n >_ - 3. Solu- tions have been found for n = 0 and all m where heat transferred from the stretching surface to the ambient. The direction and amount of heat flow were found to be dependent on the magnitude of n and m for the same Prandtl mmaber. Nusselt number increases with increasing m and Pr for uniform and variable surface tempera- ture however, for uniform surface heat flux it decreases with increas- ing m for constant Pr.
