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
