Type of article: Article
Summary
This paper provides long-term cooling tower water fouling data in seven 15.54 mm I.D. copper, helically ribbed tubes taken at low water velocity (1.07 m/s). The ranges of geometric parameters were number of rib starts (18-45), helix angle (0.33-0.55 mm), and height (25-45 °C). A series of semi-theoretical fouling correlations as a function of the product of area indexes and efficiency indexes was developed. They were applicable to different internally ribbed geometries within the above dimensional range. A series of linear multiple regression correlations was also developed. The average deviations of the two series of correlations were 4.4% and 4.8%, respectively. The correlations can be directly used to assess the fouling potential of enhanced tubes in actual cooling water situations.
