Performance of polyacrylamide as drag reduction polymer of

The drag reduction performance was investigated in a closed loop flow system. It was found that the maximum drag reduction efficiency for the new polymer/silica drag reducer was 59.2%. Compared with the neat polymer, the drag reduction efficiency was enhanced by 9.7%.

Turbulent Drag Reduction by Polyacrylamide and Other Polymers

Drag reduction increased with molecular weight, concentration and flow rate for all polymers approaching values of 70 to 80 percent and, in the case polyacrylamides, better than 25 percent drag reductions have been observed in tap water than in API brine due to the polyelectrolytic expansion of the chains in tap water.

Development and drag-reducing performance of a water-soluble

Adding a small amount of polymers can achieve significant drag reduction effects. However, for external flows, the common homogeneous mixing and diffusing injection methods are not feasible. As an alternative, the present work developed a novel water-soluble polymer composite coating. The coating made use of the film-forming property of polyvinyl alcohol with polyethyleneoxide (PEO, a well
