Resumen
El uso de tubos en espiral en intercambiadores de calor ha crecido, lo que ha hecho crecer el interés de la academia en el estudio de estos dispositivos, encontrándose que el mejoramiento en la tasa de transferencia obedece a la formación de fujos secundarios al interior de los tubos. Por tal razón, se han planteado una serie de correlaciones de transferencia de calor, desarrolladas numérica o experimentalmente, que permiten predecir la convección en los tubos en espiral y dimensionar los intercambiadores, y que son actualmente una herramienta fundamental de diseño.
Este artículo presenta las principales correlaciones que se aplican a tal fn. Aunque se experimenta mejora térmica en los intercambiadores de calor, se evidencia difcultad en el fujo, e incremento en la caída de presión, por lo que se han desarrollado y se presentan en este artículo, una serie de correlaciones para el factor de fricción. Al fnal se justifca la selección de esta tecnología y se presentan las nuevas tendencias.
