Does sulfonated polyacrylamide reduce drag in oil–water annular flow?

Moreover, the injection of the high molecular weight, sulfonated polyacrylamide (Magnafloc 1011) into oil–water annular flow in a horizontal acrylic pipe caused a maximum drag reduction of around 50% (Al-Wahaibi et al., 2007 ).

Can acrylate copolymer reduce turbulent water flow?

The effect of drag reduction of turbulent water flow by the synthesized acrylate copolymer was studied by capillary turbulent viscometry at temperatures up to 140 °C. The temperature dependence of the characteristic value of drag reduction ( fDR ), the increment in the volumetric flow rate (∆ Q) and the drag coefficient (λ) were determined.

Is acrylamide 2 acrylamido 2 methylpropane sulfonic acid a fire retardant?

Limparyoon N, Seetapan N, Kiatkamjornwong S. Acrylamide/2-acrylamido-2-methylpropane sulfonic acid and associated sodium salt superabsorbent copolymer nanocomposites with mica as fire retardants.

Is drag reduction important for a polymer with 25% charge density?

For polymer having 25% charge density (i.e. AN125 series), drag reduction is significant only for a polymer with the molecular weight of 12 million Da. with drag reduction less than 5% for polymers with molecular weights of 2 and 6–8 million Da. Using polymer with molecular weight of 12 million Da.

Does polymer flexibility increase drag reduction in multiphase flow systems?

It can be concluded that drag reduction in both single phase and multiphase flow systems is enhanced by higher polymer flexibility in solution, which can be achieved with the increase in polymer molecular weight and a decrease in charged side groups on the backbone of the polymer chain.

Does water fraction affect drag reducing polymer?

It was found that the ability of the drag reducing polymer to decrease friction loses was lowered by the decrease of the water fraction in the test section. For initially water-in-oil dispersed flow, pressure drop was not affected with the addition of the polymer.
