Abstract
Polyacrylamide (PAM) solutions are extensively used as chemical additives
or Processing aids in the manufacturing of paper and paperboard products. In
addition, they have been widely used in enhanced oil recovery. In our paper,
an experimental work has been carried out to provide a complete and
comprehensive study of the rheological properties of PAM solutions using
Brookfield viscometer DV-II. The concentrations of PAM in the tested
solutions ranged by weight from 1000 to 5000 ppm. The findings resulted in
several conclusions regarding the rheological properties of PAM solutions.
They have shown a strong shear thinning behavior for all concentrations.
Rheological characteristics of aqueous PAM solutions with shear rate ranged
between 1.29 s-l and 64.5 s-1 are investigated. A new proposed correlation for
the viscosity of PAM solution as a function of shear rate and concentration
has been suggested. The proposed correlation was found to be good fitting
with the experimental data.
