Abstract

A theoretical model is devised for calculating the limiting isothermal flow resistance in the intensification of heat transfer in tubes due to turbulence in the turbulent flow in rough pipes of small diameter. The model is valid for a wide range of Reynolds numbers, since the correlation with existing experimental data, which allows to predict the reserves of intensification of heat transfer with higher accuracy than existing methods.
