Asymptotic Analysis of the Turbulent Boundary Layer with Zero Wall Stress.

Abstract

The (so-called) continuously separating incompressible turbulent boundary layer, where the impressed pressure gradient is such as to produce zero stress at the wall, is studied by means of second-order closure of the Reynolds time-averaged equations. The closure employs an eddy viscosity which is the product of two properties of the turbulence: the mean turbulent kinetic energy and the local integral scale of the turbulence; each of these properties is described by a transport equation balancing convection, production, diffusion, and dissipation. Limit process expansions are adopted in the limit of large turbulent Reynolds number to elucidate a two-layer structure. (Modified author abstract)
