ABSTRACT

The results of generalization of experimental data for heat transfer in relaxing boundary layer downstream of a turbulent separation of any intensity in turbulized flows are presented. On the basis of analysis of determining criteria responsible for heat transfer intensification a new criterion of separation intensity Tu is proposed. This criterion is determined by the difference of kinetic turbulence energies at the edge of a dynamic boundary layer and in the external flow. Using this criterion, the similarity equation for the calculation of heat transfer intensification in relaxing turbulent boundary layer is recommended.
