“…The high price of oil and the need for increasingly higher rates of recovery foster the use of such advanced recovery techniques (Taylor and Nasr-El-Din, 1998). In addition to enhanced oil recovery, non-Newtonian fluid flow through porous media is relevant in a variety of applications, such as in polymer processing, lubrication and waste disposal applications (Chhabra et al 2001).…”

“…Apart from exhibiting shear-thinning behavior (the exception are Boger fluids), viscoelastic solutions also possess fading memory (Macosko 1994), the elongational viscosity is both strain and strain rate dependent (Petrie, 2006a, b) and in some cases largely exceeds the shear viscosity. In particular, the strain hardening behavior of the Trouton ratio (the ratio between extensional and shear viscosities) complicates substantially the analysis of viscoelastic fluid flow through a porous medium and so it is not surprising that there is little definitive and quantitative information available on the role of viscoelasticity in the flow through porous media (Chhabra et al 2001). It is the major aim of this study to contribute for an insight on this matter.…”

The Strathprints institutional repository (https://strathprints.strath.ac.uk) is a digital archive of University of Strathclyde research outputs. It has been developed to disseminate open access research outputs, expose data about those outputs, and enable the management and persistent access to Strathclyde's intellectual output. RESEARCH PAPERMicrofluidic systems for the analysis of viscoelastic fluid flow phenomena in porous media Abstract In this study, two microfluidic devices are proposed as simplified 1-D microfluidic analogues of a porous medium. The objectives are twofold: firstly to assess the usefulness of the microchannels to mimic the porous medium in a controlled and simplified manner, and secondly to obtain a better insight about the flow characteristics of viscoelastic fluids flowing through a packed bed. For these purposes, flow visualizations and pressure drop measurements are conducted with Newtonian and viscoelastic fluids. The 1-D microfluidic analogues of porous medium consisted of microchannels with a sequence of contractions/expansions disposed in symmetric and asymmetric arrangements. The real porous medium is in reality, a complex combination of the two arrangements of particles simulated with the microchannels, which can be considered as limiting ideal configurations. The results show that both configurations are able to mimic well the pressure drop variation with flow rate for Newtonian fluids. However, due to the intrinsic differences in the deformation rate profiles associated with each microgeometry, the symmetric configuration is more suitable for studying the flow of viscoelastic fluids at low De values, while the asymmetric configuration provides better results at high De values. In this way, both microgeometries seem to be complementary and could be interesting tools to obtain a better insight about the flow of viscoelastic fluids through a porous medium. Such model systems could be very interesting to use in polymer-flood processes for enhanced oil recovery, for instance, as a tool for selecting the most suitable viscoelastic fluid to be used in a specific formation. The selection of the fluid properties of a detergent for cleaning oil contaminated soil, sand, and in general, any porous material, is another possible application.

“…However, in their 2001 review, Chhabra et al [41] pointed out the persistent lack of definitive and quantitative information available on the role of viscoelasticity and of the effects arising from polymer/wall interactions, polymer retention, etc. Accordingly, from the results of frontal filtration experiments involving non-diluted solutions of polyacrylamides, Surý and Machač [42] stress on the significant contribution of polymers viscoelasticity (due to extensional deformations) to the control of the filtration process.…”

“…The dispersion of a fluid in a porous media indicates the degree of interconnectivity of the pore space and provides an insight into the morphological characteristics of the porous medium. A large number of dispersion experiments in porous media have been conducted on Newtonian and non-Newtonian fluids [43]. The Péclet number (P e) is the ratio of advective to diffusive forces that characterizes dispersion in porous media and can be written [44] …”

Abstract. The displacement scale dependent molecular dynamics of solvent water molecules flowing through β-lactoglobulin gels are measured by pulse gradient spin echo (PGSE) nuclear magnetic resonance (NMR). Gels formed under different pH conditions generate structures which are characterized by magnetic resonance imaging (MRI) and PGSE NMR measured dynamics as homogeneous and heterogeneous. The data presented clearly demonstrate the applicability of the theoretical framework for modeling hydrodynamic dispersion to the analysis of protein gels.
