The lecture summarizes the development of a physical model for transfer processes in the near-wall region of some complex flows occurring in technological applications such as impinging jets, heat transfer of cylinders in cross flow and in tube banks, in packed beds where processes manifest properties characteristic for turbulent separated flows. This allows them to be classified under turbulent separated flows. The application of a similarity theory of the near-wall zone of turbulent separated flow has brought to a fundamental limiting universal "two-thirds power law". The existence of the limiting heat and mass transfer law provides an explanation to many experimentally observed facts and correlations, and may serve as a basis for the experimental data generalization; the fact that the spectra, velocity and temperature profiles are in accord with the similarity laws of turbulent separated flows can be used for verification of the validity of turbulence models implemented.
