RÉSUMÉ

Equilibrium and quasi-equilibrium flows in a two-dimensional turbulent boundary layer of an incompressible fluid are considered. For these regimes with the help of the experimental data for the Clauser velocity profile parameter G, a two-parametric function G(β,H) was obtained, where β (the Clauser parameter) is the non-dimensional velocity gradient and H is the ratio of the displacement thickness to the momentum thickness. This relationship allows the problem of computing the aforementioned flows to be closed. The region of maximally allowable values of H(G), where the obtained results are valid, was determined.
