Abstract

Abstract

An analysis of the steady two-dimen sional non-Newtonian flow on a power-lawstretched surface with suction or injection was considered. The thermal conductivity was assumed to vary as a linear function of temperature. The transformed governing equations in the present study were solved numerically by using the Runge-Kutta method. Some of the results obtained for a special case of the problem were compared to the results published in a previous work and were found to be in excellent agreement. Two cases were considered, one corre-sponding to a cooled surface temperature and the other, to a uniform surface temperature. The numerical results show that variable thermal conductivity parameter B, injection parameterd and the power-law indexn have sign ificant in fluences on the temperature profiles and the Nus-seltnumber in the above two cases.
