Abstract:

The drag reduction, mean flow, and turbulence properties of several concentrations of Separan AP30 and water in a fully developed turbulent pipe flow were studied using a two-conpoment laser-Doppler anemometer. This measurement technique was chosen because of its inherent advantages over the traditional measuring techniques that have been used in previous studies of drag reducing flows. A polymer injection technique was used. A slurry of methanol and polymer powder was injected directly into the flowing water, providing a fresh, unaged polymer solution.
