This article describes three recent developments in the theory and associated computations of separating and transitional boundary layers. The three developments, which are very much inter-related, concern the following: a reversed-flow breakdown in the solution of the steady interacting boundary-layer equations; a finite-time break-up possible in any unsteady interactive boundary layer; and the absence of large-scale separation in turbulent flow. The aerodynamic implications for stall, intermittency, transition and turbulence effects are also emphasized.
