A Procedure For Calculating The Development Of Turbulent Boundary Layers Under The Influence Of Adverse Pressure Gradients

A procedure based on the kinetic-energy equation and an extended form of the momentum equation has been devised for calculating the development of turbulent boundary layers in adverse pressure gradients. Predictions, by this method, of turbulent-boundary-layer developement in comparison with experimental results from several sources are presented for a number of cases of flow over flat plates and airfoils and in conical diffusers. In the range of boundary-layer flow short of separation, the agreement with experiment is, in most cases, quite satisfactory; in some instances, however, there is definite disagreement between the calculated and experimental results. It is believed, however, that good agreement has been obtained of effort along the present lines, particularly with respect to improvement of the correlations and refinement of the equations.
