HEAT TRANSFER IN SMOOTH TUBES WITH TURBULENT FLOW.

The question of heat transfer in smooth tubes is of great practical importance for the thermal power industry. In heat exchangers in the power industry flow regime is mainly turbulent; these heat exchangers use relatively long tubes and donditions of stabilized heat transfer are therefore satisfied. Results have been published both of theoretical solutions to this problem, and of experimental investigations. This paper compares experimental data with results of calculations to show the relationship of Prandtl, Nusselt and Reynolds numbers for a range of exchanger parameters.
