Abstract

Incompressible turbulent boundary layer problems are solved based on certain assumed boundary conditions, by integrating Prandtl integral equation. Representing the velocity profile parameter as a function of dimensionless similarity number of turbulent boundary layers, a separation criteria can be achieved. This helps in solving the attached boundary layers with max mum deceleration.
The obtained theoretical results are compared with previous available experimental data obtained for radial diffuser.
Moreover, this investigation contains relation between the turbulent velocity profile and shear stress profile in a parametric form for equilibrium  boundary layers and agree well with that obtained from Mellor-Gibson theory.
