It has become important to improve the heat transfer characteristics of tubes in view of the energy situation and to avoid the issues of imminent energy lack with suitable and well functional precautions. A lot of methods to enhance heat transfer have been developed, among which 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 passive technique involving so many ways like twisted tapes, fins, ribs, rough surface, additives, extended surfaces, wire coil insert and corrugations.
