The asymptotic structure of turbulent separating flows

The present work shows how a direct application of Kaplun limits to the problem of turbulent separating flows can explain in simple terms how the two-layered asymptotic structure reduces to a new structure consistent with the local solutions of Goldstein and of Stratford at a point of zero wall shear stress. The present arguments use in addition a scaling algebraic equation that is derived from the first principles through some order of magnitude reasonings.
