Heat Exchanger, friction factor, Colburn factor, Reynolds number
In recent years, thousands of numerical and experimental studies have been performed on heat exchangers with different configurations. Mainly heat transfer and frictional characteristics have been studied in detail with respect to different geometrical parameters in various ranges of Reynolds number. Further these studies have been cross verified with researches already performed in this field. With the advent of new tools like CFD for the study of thermo-hydraulic characteristics, it has becomes easier to understand flow phenomena around the tubes for different rows and also in rest of flow regions. These studies also bring about some correlations so as to easily find the values of Colburn and friction factor for various different geometrical parameters so as to suit to the different industrial conditions and requirements.
