Abstract

A new theoretical model is developed to compute extreme values for heat transfer and hydraulic resistance in the conditions of intensification in tubes by means of artificial flow turbulization for gas heat-carrying mediums with variable thermophysical properties. The model describes corresponding processes for a wide range of Reynolds and Prandtl numbers. Obtained results allow to predict enhancement reserves for non-isothermic heat transfer.
