Comparative studies of rheological properties
The present work is concerned with experimental results of rheological characteristics of polyacrylamide (PAM) and of partially hydrolyzed polyacrylamide (HPAM) (degree of hydrolysis up to 80%) in aqueous and aqueous/sodium chloride solutions with changing experimental conditions such as polymer concentration, temperature, solvent quality, and shear rate applied.
In addition, they have been widely used in enhanced oil recovery. In this thesis, an experimental work has been carried out to provide a complete and comprehensive study of the rheological properties of polyacrylamide solutions using cone-and-plate rheometery. Polyacrylamide concentrations in the tested solutions ranged by weight from 2 to 5%.
The rheological properties of aqueous polyacrylamide solutions
Polyacrylamide 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 this thesis, an experimental work has been carried out to provide a complete and comprehensive study of the rheological properties of polyacrylamide solutions using cone-and-plate
The rheological behavior of the polyacrylamide solution were studied over the 20–50 ppm range and the temperature range of 20–50°C. Fig. 1, Fig. 2 show the experimental results of the shear stress (τ) and shear rate (γ ̇) and indicate the non-Newtonian behavior of these solutions. Fig. 1 shows the experimental results obtained for the polyacrylamide solution at 50°C at different

This work aims to improve the rheological properties of partially hydrolyzed polyacrylamide (HPAM) for enhanced oil recovery by using silica (or silicon dioxide, SiO2) nanoparticles (NPs). Novel aqueous HPAM-based SiO2 nanocomposites were formulated, and their rheological properties were investigated under different salinities, temperatures, and aging times.
Effect of shearing actions on the rheological properties
The mesostructures of aqueous solutions (one simple type of water-based drilling fluids), with a kinetic hydrate inhibitor (polyvinyl pyrrolidone, PVP) or/and drilling fluid additive (sodium carboxymethyl cellulose, CMC), and their rheological properties after two shearing actions (600 r/min and 6000 r/min) were respectively investigated using a scanning electronic microscope (SEM) and a six
Rheological Properties of Cream Cheese Cream cheeses clotted with the fruits of S. elaeagnifolium had spreadability values comparable to those coagulated with chymosin (the control cheese). However, the viscoelastic properties of the cream cheeses varied significantly depending on the coagulant and volume of coagulant used ( Table 3 ).
