摘要：
An experimental study of friction reduction and polymer degradation in turbulent pipe flow is described for dilute water solutions of guar gum, CMC, Separan NP-10 and Polyox WSR-301. The tests are made in a turbulent-flow rheometer with a 2 mm I. D. pipe over a Reynolds number range from 8,000 to 25,000. The maximum attainable friction reduction for guar gum, Separan NP-10 and Polyox WSR-301 is found to be almost equal, but large differences in effectiveness occur. It was found that contrary to published data for guar gum, this material is not very stable.
