| Abstract |
The drag reduction(DR) of non-ionic surfactant and polymer according to the variation of fluid velocity, temperature and surfactant concentration was investigated experimentally. For this experiment, the kind of surfactant was non ionic amine-oxide and the kinds of polymer were polyacrylamide and xantan gum. An experimental apparatus equipped with one water storage tanks was built and two flow meters, two pressure gauges for data logging system was installed. Results showed that the kinds of polymer, polyacrylamide and xantan gum, had DR of below 20% for below 500 ppm in fluid temperature of 50～80℃. But the kind of surfactant, amine oxide, had DR of above 40% for 500～1000 ppm in fluid temperature of 50～80℃. As a result, amin oxide showed better materials to use to the district heating system. |
