THE EFFECT OF HIGH-MOLECULAR-WEIGHT POLYMER ADDITIVES ON THE PERFORMANCE OF A CONICAL DIFFUSER.
Abstract
Experiments were conducted to obtain and compare conical-diffuser performance information using plain tapwater and high-molecular-weight polymer solutions. The diffuser exhibited a transitory-type separation with plain water. Test results showed that diffuser performance increased by approximately 7 to 9 percent when using J2-FP guar gum solution concentrations of 1/64 to 1/8 percent over a Reynolds-number range of 55,000 to 75,000. The experiments also revealed that large-scale pressure fluctuations might be greatly decreased by the use of these solutions. (Author)
