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 …

Drag reduction has constantly received great attention due to its extensive range of
applications in fluid transportation and vehicle industries. The vital role of two different …

Three types of relatively high-molecular polymer were used to investigate drag reduction in
single-phase flow through a horizontal, 12.7-mm pipe. Diesel oil and a mixture of diesel oil …

Flow patterns are important for pressure gradient calculation and corrosion protection. In this
study, the characteristics of oil–water flow were investigated in a horizontal acrylic pipe with …

Particle image velocimetry (PIV) measurement technique provides an excellent opportunity
for investigating instantaneous spatial structures which are not always possible with point …

Five linear, water-soluble, sulfonated polyacrylamides of relatively high molecular weights
were used to investigate drag reduction in oil–water multiphase flow through a horizontal …

The effects on velocity and turbulent properties of drag reducing polymers added in the
water phase of oil-water flows were studied with Particle Image Velocimetry (PIV). The …

The effects of drag-reducing polymers on the flow patterns, pressure gradients, and drag-
reducing rates of oil–water two-phase flows were investigated using a horizontal acrylic pipe …

Horizontal oil-water two-phase flows are frequently encountered in many industrial
processes but the understanding of the dynamic behavior underlying the different flow …

An experimental investigation of the effect of various mixtures of different polymers on drag
reduction was studied in a dispersed horizontal oil-water flow. The study was carried out in a …
