ABSTRACT
The use of wire coils was the first attempt of enhancing heat transfer in tubes of tubular heat exchangers made in the middle of the nineteenth century by Joule. According to García et al. (2012), those works are considered as the pioneering in the field of heat transfer intensification. Much later, at the end of the 1950s, the researches on heat transfer augmentation using “repeated-rib” roughness in turbulent pipe flow that are analysed in paper by Webb et al. (1971) have started. In the 1970s, the technology to manufacture not expensive deformed tubes was developed and in the 1980s dimpled and corrugated by cold external deformation tubes. These developments were stipulated by a need of more compact and efficient heat exchangers. To improve the performance of heat transfer surfaces with small elements on the wall, which induce artificial turbulence in the flow, a large number of researches were conducted with their results presented in literature of the last decades.
