Fouling of Augmented Heat Transfer Tubes

Abstract

Comparisons are made between fouling of augmented and plain heat transfer tubes. Results from the literature are analyzed on a consistent basis to emphasize differences between extended and enhanced surfaces. Tubes with internal and external fins are considered, as well as different types of enhanced tubes. Based on the analysis of this data, recommendations are given for assigning fouling resistances for augmented tubes in terms of the corresponding plain-tube fouling resistances.
