Part of the Lecture Notes in Physics book series (LNP, volume 235)


The turbulent Couette flow is considered from the point of view of the asymptotic theory for turbulent shear flows at large Reynolds numbers. According to this theory the flow has a two-layer structure which can be treated by the method of matched asymptotic expansions. Without specifying a turbulence model the analysis leads to boundary conditions which have to be satisfied by the solution and hence by any turlence modelling. It is shown that some of the existing turbulence models do not satisfy these conditions. A new turbulence model is proposed which leads to analytical solutions.
