Abstract

Numerical solutions for the velocity and temperature fields have been obtained to determine fully developed friction factors and Nusselt numbers. The friction factor increases markedly as a function of the Reynolds number Re_w based on the velocity of the moving wall. The effect of Re_w on the Nusselt number depends on the Prandtl number. At higher Prandtl numbers, there is a significant increase in the Nusselt number with Re_w. For intermediate Prandtl numbers, the variation of the Nusselt number with Re_w is rather small.
