The streamwise evolution of a turbulent boundary layer (TBL) developing under constant pressure on a smooth wall is considered. The closure problem is described for the zero pressure gradient (ZPG) flow where the only assumptions made are the use of classical similarity laws, such as Prandtl's law of the wall and Coles'[1, 2] law of the wake, together with the mean continuity and mean momentum differential and integral equations. The important parameters are identified and the problem is reduced to one semi-empirical input with the assumption that the Reynolds shear stress can be described by a two-parameter family. Good agreement is shown with the experimental data.
