Long-term degradation of high molar mass poly(ethylene oxide) in a turbulent pilot-scale pipe flow

The long-term drag reduction capability of poly(ethylene oxide) with a nominal molar weight of M w = 4 × 10 6 g/mol dissolved in water was investigated in a pilot-scale pipe flow device (inner diameter of test section 26 mm) at a Reynolds number of 105. A total loss of the initially high (75%) drag...
