GENERALIZATION OF REZULTS OF EXPERIMENTAL AND NUMERICAL STUDY OF HEAT TRANSFER IN FLOWS WITH INCREASED EXTERNAL TURBULENCE ON THE BASES OF TWO-PARAMETER MODELS OF TURBULENCE
Abstrakt
The scheme of allowing for the effect of the external flow turbulence on intensification of heat transfer and friction in the wall boundary layers is presented.
It is supposed that the external turbulized flow possesses the effective viscosity and thermal conductivity characteristic of its internal structure.
These parameters are determined on the bases of two-parameter models of turbulence among which the models "energy-scale" and "energy-dissipation" are the
most preferable.
