The effect of drag‐reducing agents (DRAs) on fluid flows in straight pipes has been well
documented. Key among these is the effect of DRAs on turbulence statistics (Reynolds …

The economic and engineering importance of additive drag reduction (DR) has provided
motivation and wealth of data on the phenomena in straight conduit flows. Study into the …

Drag reduction (DR) by additives in single-and two-phase fluid transport has enormous
engineering and economic benefits. An ample amount of work has been done with regards …

The synergistic effect of natural and synthetic polymers as drag reducing agents in water
phase during horizontal oil-water flows was studied in 12 mm internal diameter (ID) …

This paper presents an investigation into the influence of drag-reducing polymer (DRP) on
the flow of water inside and around U-bends. The DRPs tested were partially hydrolysed …

This study was carried out to investigate the effect of pipe diameter and temperature on the
effectiveness of polyethylene oxide as drag reducing polymer. The flow facility is made from …
