The enhanced tube is a kind of the passive technique for improving the thermal performance of the heat exchangers with a little increase of the friction penalty. They have stated to use instead of the common smooth tubes for designing of the heat exchangers. The size of these heat exchangers can be reduced considerably by using the enhanced tubes instead of smooth tubes. Normally, they are divided into four groups: the corrugated tube, ribbed tube, grooved tube, and fluted tube. Compared with the common smooth tube, many researchers reported that use of the enhanced tubes dramatically increases the heat-transfer performance, both theoretically and experimentally. Focusing on the advantages of the enhanced tubes, this article summarizes the published studies on the heat-transfer and pressure-drop characteristics of the enhanced tubes, both experimental and quantitative investigations.

“…Ravigururajan and Bergles [3] presented the general correlations for friction factor and heat transfer coefficient for single-phase turbulent flow in internally augmented tubes. Kang et al [4] developed the flooding correlation for a fluted tube with a twisted insert. Effects of the twisted tape insert and the angle of inclination on flooding were examined.…”
