Thermal transfer analysis of tubes with extended surface with fractal design

Heat exchangers are formed by tubes with extended surfaces that improve the transfer of heat between two media (e.g., a solid and a liquid in motion). This paper presents the design of an extended surface tube with fractal geometry, corresponding to the Koch snowflake and the Cesaro curve. For the d...

This paper presents the design of an extended surface tube with fractal geometry, corresponding to the Koch snowflake and the Cesaro curve. For the design, we used the CAD computational tool, and afterwards we performed the CAE finite element analysis and verified the thermal behavior of the designed tube. We were able to reduce the heat transfer time and increase the heat flow in the system in the following manner: for smooth tube, 250 W/m2; for Koch surface, 500 W/m2; for six fins, 1450 W/m2; and for Cesaro curve, 3600 W/m2. These results demonstrate the limits of the design and the advantages of its implementation in machinery such as condensers, heat exchangers, and boilers.Los intercambiadores de calor están conformados por tubos con superficies extendidas, con el propósito de mejorar la transferencia de calor entre dos medios, que pueden ser un sólido y un líquido en movimiento. En el presente trabajo se expone el diseño que se llevó a cabo de un tubo de superficie extendida con geometría fractal, correspondiente al copo de koch y la curva de Cesaro, con la herramienta computacional CAD, para luego realizar el análisis por elementos finitos CAE y verificar el comportamiento térmico del tubo diseñado. Se logró obtener como resultado reducir el tiempo de transferencia de calor y aumentar el flujo de calor en el sistema del modo siguiente: para tubo liso, 250 W/m2; para superficie de Koch, 500 W/m2; para seis aletas, 1450 W/m2, y, finalmente, para curva de Cesaro, 3600 W/m2. Todo ello, permitió evidenciar los límites del diseño y las ventajas que pueden llegar a tener respecto a su implementación en maquinarias como condensadores, intercambiadores de calor y calderas.application/pdfapplication/xmlengengUniversidad Pedagógica y Tecnológica de Colombiahttps://revistas.uptc.edu.co/index.php/ingenieria/article/view/7749/6139https://revistas.uptc.edu.co/index.php/ingenieria/article/view/7749/7183Copyright (c) 2018 Luis Eduardo Llano-Sánchez, Darío Manuel Domínguez-Cajeli, Luis Carlos Ruiz-Cárdenashttp://purl.org/coar/access_right/c_abf83http://purl.org/coar/access_right/c_abf2Revista Facultad de Ingeniería; Vol. 27 No. 47 (2018); 31-37Revista Facultad de Ingeniería; Vol. 27 Núm. 47 (2018); 31-372357-53280121-1129boilersCesaro curvefinite elementsfractal designheat transferKoch Snowflaketubes with extended surfacecalderascopo de Kochcurva de Cesarodiseño fractalelementos finitostransferencia de calortubos de superficie extendidaThermal transfer analysis of tubes with extended surface with fractal designAnálisis de transferencia térmica de tubos con superficies extendidas con diseño fractalresearchinvestigacióninfo:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/publishedVersionhttp://purl.org/coar/version/c_970fb48d4fbd8a166http://purl.org/coar/version/c_970fb48d4fbd8a85Llano-Sánchez, Luis EduardoDomínguez-Cajeli, Darío ManuelRuiz-Cárdenas, Luis Carlos001/14205oai:repositorio.uptc.edu.co:001/142052025-07-18 11:53:14.475metadata.onlyhttps://repositorio.uptc.edu.coRepositorio Institucional UPTCrepositorio.uptc@uptc.edu.co
