LIMITING INTENSIFICATION OF HEAT EXCHANGE IN TUBES DUE TO ARTIFICIAL TURBULIZATION OF THE FLOWG. A. Dreitser and I. E. Lobanov UDC 536.27 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.
