Passive heat transfer enhancement review in corrugation

The heat transfer is a very interesting field for economical, functional and environmental reasons; it is almost related to each aspect of human lives. Therefor, the enhancement of such field is quite essential. Passive heat transfer represents is the soul of heat transfer enhancement due to the merits of simplicity, cheap and good enhancement with acceptable pressure drop. Corrugation is a method involved within the passive techniques of enhancement, it is important and being adopted in a wide range of applications like a nuclear reactor cooling, refrigeration, heat exchangers, and other industrial applications. The current article presents an extensive review of numerical and experimental studies on heat transfer enhancement, which covers the laminar and turbulent flow regions in the corrugations, especially in corrugated tubes. This paper dealt with 95.74% of papers published in corrugated tubes for different applications to offer one article representing a database stop for the designers and authors whom concerning and dealing with heat transfer enhancement in corrugated tubes.
