OF THE FLOW

A theoretical model for calculating the limiting isothermal 
parameters of heat exchange and resistance under the conditions of 
intensification of heat exchange in tubes due to turbulization of 
the flow has been developed. The model describes the corresponding 
processes for a wide range of Reynolds and Prandtl numbers, which 
enables one to predict the limits of intensification of heat exchange 
with a much higher degree of accuracy than the existing methods.
