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…
Flow-history-dependent orientational relaxation in dilute polydisperse colloidal rod suspensions
Yuto Yokoyama, Vincenzo Calabrese, Fabian Hillebrand +3
Orientation and relaxation dynamics of rod-like colloids under flow govern the optical and mechanical properties of many emerging soft materials. In polydisperse suspensions, parti…
Effects of fluid rheology and geometric disorder on the enhanced resistance of viscoelastic flows through porous media
Simon J Haward, Amy Q Shen
Recent works reveal the importance of chaotic flow fluctuations as a mechanism for the enhanced resistance observed in viscoelastic porous media flows, and also show how chaotic fl…
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…
