摘要：

This paper describes a new technique used to quantify waterside fouling and evaluate the performance of a heat transfer tubing. Experiments were carried out at constant operating conditions (Re = 290, input power = 1000 W ) for 50 hours, and data were recorded every one hour. The fouling thermal resistance and the thermal efficiency of the tubing test section were determined. Results show that fouling accumulation rate increases as the working surface temperature increases. Moreover, fouling shows a significant effect on the thermal efficiency, where a total drop of 27% in the thermal efficiency of the test section was recorded during the test period.
