Popis:	An analysis is presented for fully developed transitional turbulent flow between parallel plates that features the use of a turbulent burst model for the important wall region. Model closure is accomplished by the specification of the mean burst frequency and, for moderate to high Reynolds numbers, by matching with a classical eddy viscosity model for the turbulent core. Predictions obtained for friction factor and mean velocity distribution are compared with experimental data for fully developed transitional turbulent flow in a channel with large aspect ratio. Predictions are also developed for the eddy viscosity within the wall region for transitional turbulent conditions.
