Abstract

Recent advances in the application of asymptotic methods to the analysis of turbulent wall-bounded shear flows in the limit of large Reynolds number are surveyed. In particular, we consider (i) the turbulent wake downstream of sharp and wedge-shaped trailing edges, (ii) turbulent boundary-layer flow under the influence of a large and adverse pressure gradient and the related turbulent separation problem, and (iii) three-dimensional turbulent boundary-layer flow. The above are discussed in the context of incompressible flow. The emphasis is on contributions from the USA; however, related work elsewhere is also discussed.
