“…In the region of closed streamlines, the constitutive equation (10) is integrated over the closed loops repeatedly until the stress changes by less than 0.1% in one cycle before the particle-polymer stress and stresslet are computed. We determine the linearized stress 1L on a fixed Eulerian grid by integrating (22) over the streamlines of the undisturbed flow and interpolate to obtain 1L on the streamlines of the full velocity field when computing the volume integral of 1N . While 1 is a smooth function of position at all De, the linearized polymer stress has a boundary layer of thickness De inside and outside of the particle surface when De 1.…”

“…The consideration of the Oldroyd-B constitutive equation for the rheology of the suspending fluid has several advantages for the present study. A well established experimental formulation known as a Boger fluid, consisting of a dilute solution of high molecular weight polymers in a viscous Newtonian fluid, yields rheology consistent with the equation [20][21][22]. A kinetic theory based on a Hookean dumbbell model of the polymers yields the Oldroyd-B constitutive equation [23].…”

The influence of particle-polymer interactions on the ensemble average stress is derived as a function of the Deborah number for a dilute suspension of spheres in an Oldroyd-B fluid in the limit of small polymer concentrations. The slow rate of decay of the particle-induced polymer stress with separation from a particle presents a challenge to the derivation of the average stress, which can be overcome by removing the linearized polymer stress disturbance before computing the bulk average stress from the particle-induced disturbance. The linearized stress can be shown to have zero ensemble average. The polymer influence on the particle's stresslet is computed with the aid of a generalized reciprocal theorem based on a regular perturbation from Newtonian flow for small polymer concentration. The analysis shows that the particle-polymer contributions to the shear stress and first normal stress difference shear thicken as has been observed in the experiments of Scirocco et al.[Shear thickening in filled Boger fluids, J. Rheol. 49, 551 (2005)]. The particle-polymer contribution to the second normal stress difference is positive at small Deborah numbers but changes sign at a Deborah number of about 2.3.

“…Canella et al achieved a satisfactory match with their experimental results by using a constant value of 6 for β, although this value far exceeds correction factors suggested by other researchers [28][29][30]. Even though all published results in the literature are not covered by using this correction factor, better agreement between analytical and experimental results was obtained, such as in experiments performed by Teeuw and Hesselink [15] and Gogarty [31].…”

Polymer flooding is one of the most successful chemical EOR (enhanced oil recovery) methods, and is primarily implemented to accelerate oil production by sweep improvement. However, additional benefits have extended the utility of polymer flooding. During the last decade, it has been evaluated for use in an increasing number of fields, both offshore and onshore. This is a consequence of (1) improved polymer properties, which extend their use to HTHS (high temperature high salinity) conditions and (2) increased understanding of flow mechanisms such as those for heavy oil mobilization. A key requirement for studying polymer performance is the control and prediction of in-situ porous medium rheology. The first part of this paper reviews recent developments in polymer flow in porous medium, with a focus on polymer in-situ rheology and injectivity. The second part of this paper reports polymer flow experiments conducted using the most widely applied polymer for EOR processes, HPAM (partially hydrolyzed polyacrylamide). The experiments addressed highrate, near-wellbore behavior (radial flow), reservoir rate steady-state flow (linear flow) and the differences observed in terms of flow conditions. In addition, the impact of oil on polymer rheology was investigated and compared to single-phase polymer flow in Bentheimer sandstone rock material. Results show that the presence of oil leads to a reduction in apparent viscosity.

“…Onset of extensional viscosity, the transition point between shear dominant and extensional dominant flow, depends on polymer, solvent and porous media properties. Effects of polymer properties on extensional viscosity may be investigated by using special rheometers that only generate pure extensional flow [44][45][46][47][48][49][50][51][52][53]. In the following, effects of polymer, solvent and porous media properties on the onset of extensional viscosity are explained.…”

Polymer flooding is one of the most successful chemical EOR methods, and is primarily implemented to accelerate oil production by sweep improvement. However, other benefits have extended the utility of polymers. During the last decade, it has been evaluated for an increasing number of fields, both offshore and onshore. This is a consequence of improved polymer properties, which extends the use to HTHS (high temperature high salinity) conditions and of improved understanding of flow mechanisms such as for heavy oil mobilization. A key issue in understanding polymer performance is to control and predict in-situ porous medium rheology. The first part of this paper reviews recent developments in understanding polymer flow in porous medium. Especially, polymer in-situ rheology and injectivity is discussed. The second part of this paper reports polymer flow experiments using the most applied polymer for EOR processes, HPAM (partially hydrolyzed polyacrylamide). The experiments address high rate near-wellbore behavior (radial flow) as well as reservoir rate steady state flow (linear flow) and discuss differences observed in terms of flow conditions. In addition, impact of oil on polymer rheology was investigated, and compared to single-phase polymer flow in Bentheimer sandstone rock material.
