摘要

Abstract

This paper provides a comprehensive analysis on cooling tower fouling data taken from seven 15.54 mm I.D. helically ribbed

copper tubes and a plain tube at Re = 16000. There are two key processes during fouling formation: fouling deposition and fouling removal

which can be determined by mass transfer and fluid friction respectively. The mass transfer coefficient can be calculated through three analogies: Prandtl analogy

Von-Karman analogy

and Chilton-Colburn analogy. Based on our analyses

Von-Karman analogy is the optimized analogy

which can well predict the formation of cooling tower fouling. Series of semi-theoretical fouling correlations as a function of the product of area indexes and efficiency indexes were developed

which can be applicable to different internally ribbed geometries. The correlations can be directly used to assess the fouling potential of enhanced tubes in actual cooling tower water situations.
