Abstract : A numerical technique was developed for incompressible turbulent channel flows which predicts the entire flow field downstream of any initial station. The technique includes any of the flow fields from a two-dimensional confined ejector region to the fully developed turbulent flow regime. The continuity, momentum, four one-point velocity correlations and a volumetric constraint equation are used as the fundamental governing equations. Closure is achieved by using Donaldson's Invariant Models which requires the specification of six constants to accommodate the experimental data. (Modified author abstract)
