Velocity and temperature profiles were computed for turbulent flow, both in the entrance region and the fully developed state, in a duct with heated parallel plates. By starting the calculations at the duct inlet and using a finite difference technique and a three-dimensional mixing length originally defined for corner flows, it was possible to predict axial flow behavior and the nonasymptotic approach to fully developed flow with and without associated heat transfer.
