Polymer extension at stagnation points governs flow thickening of polymer solutions in ordered porous media
Emily Y. Chen, Simon J. Haward, Amy Q. Shen +1
Polymer solutions exhibit anomalous flow thickening -- marked by an abrupt increase in the macroscopic flow resistance -- above a threshold flow rate in a porous medium, but not in…
Elastic instability of wormlike micelle solution flow in serpentine channels
Emily Y. Chen, Sujit S. Datta
Wormlike micelle (WLM) solutions are abundant in energy, environmental, and industrial applications, which often rely on their flow through tortuous channels. How does the interpla…
Stagnation points at grain contacts generate an elastic flow instability in 3D porous media
Emily Y. Chen, Christopher A. Browne, Simon J. Haward +2
Many environmental, energy, and industrial processes involve the flow of polymer solutions in three-dimensional (3D) porous media where fluid is confined to navigate through comple…
Harnessing an elastic flow instability to improve the kinetic performance of chromatographic columns
Fabrice Gritti, Emily Y. Chen, Sujit S. Datta
Despite decades of research and development, the optimal efficiency of slurry-packed HPLC columns is still hindered by inherent long-range flow heterogeneity from the wall to the c…
Influence of fluid rheology on multistability in the unstable flow of polymer solutions through pore constriction arrays
Emily Y. Chen, Sujit S. Datta
Diverse chemical, energy, environmental, and industrial processes involve the flow of polymer solutions in porous media. The accumulation and dissipation of elastic stresses as the…
