Asymptotic Analysis of Two—Dimensional Turbulent Separating Flows

Chapter
Part of the Notes on Numerical Fluid Mechanics (NNFM) book series (NONUFM, volume 40)

Summary

A universal law of the wall is developed by applying asymptotic theory for turbulent flows at high Reynolds numbers. This law is valid for attached as well as for separated flows and hence describes correctly the change of the law of the wall from attached to separated flows. This change is demonstrated for two examples: Couette—Poiseuille flows and equilibrium boundary layers.

The asymptotically correct flow resistance formulae for the Couette—Poiseuille flows are developed by applying an indirect turbulence model in addition to the universal law of the wall. The results for the equilibrium boundary layers are used to develop an integral method for calculating turbulent boundary layers including those with separation. The theoretical results are compared with experiments.
