FRICTION REDUCTION AND DEGRADATION IN TURBULENT FLOW OF DILUTE POLYMER SOLUTIONS

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.
