Аннотация

Experimental investigations have been carried out on heat transfer and pressure drop for turbulent flow of air in a smooth tube and helical-coil-inserted tubes. The pitch s, the length L and the position of the helical coil x in the tube were varied. By means of dimensional analysis and experimental results the correlations for the Nusselt number Nu and friction factor for helical coil ξHC were developed.
