Abstract : It is now widely recognized that the steady boundary layer equations can be used to predict small regions of flow separations when the interaction with the outer inviscid flow is allowed for. A very close relationship between the formalism of the finite Reynolds number approach of treating the interacting boundary layer equations and the socalled triple deck approach to unravel the structure of asymptotic high Reynolds number interacting shear layers is also now widely accepted. The alternative procedure of approaching the problem numerically via the ensemble-averaged Navier-Stokes equations is possible, and the steady interacted boundary layer approach is attractive when numerical solutions of the interacted boundary layer equations are of sufficient generality and can be routinely obtained accurately and more efficiently than solutions of the Navier-Stokes equations.
