A boundary layer maintained as close as possible to separation over an extended distance was produced, in accordance with the concept of Stratford. The results comprise the first comprehensive study of a Stratford type flow and are intended to assist in the development of turbulence models for flows close to separation. The resulting layer exhibited a nearly constant shape factor of 2.5 and approximately linear streamwise growth of the integral length scales. The flow exhibited a definite non-equilibrium character, indicated by the differing scales required for collapse of the mean velocity and turbulence intensity profiles. Application of the linear stability theory predicted a most amplified frequency in reasonable agreement with experimental spectral results.
