LLANO-SANCHEZ, Luis Eduardo; RUIZ, Luis Carlos; DOMINGUEZ-CAJELI, Darío Manuel  e  MELO-DE-ALONSO, Martha Cecilia. Design of longitudinal Finned tubes adjusted with the Cesàro curve. Rev. Fac. ing. [online]. 2018, vol.27, n.48, pp.71-78. ISSN 0121-1129.  https://doi.org/10.19053/01211129.v27.n48.2018.8104.

This paper proposes a process of higher heat transfer efficiency, through a fractal design over Cesaro curve as an extend surface for an exchange tube. Our designs yielded better results applying finite element analysis compared with the smooth surface commonly used in the industry. This new adaptation can be oriented toward applications involving gases and viscous liquids, for devices such as motors, boilers and dissipaters, among others.

Palavras-chave : Cesàro curve; fractal geometry; heat exchangers; heat transfer; longitudinal extended surfaces.
