Separated boundary layers, such as those on the suction surface of airfoils at high angles of attack or in rapidly expanding diffusers, are considered. A finite-difference procedure is outlined which solves the flow equations in general orthogonal coordinates, thus facilitating the treatment of curved surfaces: the kappa-epsilon, two-equation turbulence model is used. Calculations of separated boundary layers in curved diffusers are presented from which the influence of geometric and turbulence model paramters are determined. (DePo)
