A viscous solvent laminar flow may be strongly modified by the addition of a tiny amount of
long polymer molecules, resulting in a chaotic flow called elastic turbulence (ET). ET is …

Polymer solutions are frequently used in enhanced oil recovery and groundwater
remediation to improve the recovery of trapped nonaqueous fluids. However, applications …

We formulate a low-storage method for performing dynamic mode decomposition that can
be updated inexpensively as new data become available; this formulation allows dynamical …

Complex and active fluids find broad applications in flows through porous materials.
Nontrivial rheology can couple to porous microstructure leading to surprising flow patterns …

Viscoelastic flows through microstructured geometries transition from steady to time
dependent and chaotic dynamics under critical flow conditions. However, the implications of …

Polymer solutions are often injected in porous media for applications such as oil recovery
and groundwater remediation. As the fluid navigates the tortuous pore space, elastic …

Although concussion is one of the greatest health challenges today, our physical
understanding of the cause of injury is limited. In this Letter, we simulated football head …

We experimentally investigate the flow of a viscoelastic fluid in a parallel shear geometry at
low Reynolds number. As the flow becomes unstable via a nonlinear subcritical instability …

There are so many non-Newtonian fluids in our daily life, such as milk, blood, cytoplasm,
and mucus, most of which are viscoelastic heterogeneous liquid containing cells, inorganic …

Electroosmotic flow (EOF) has been widely used in various biochemical microfluidic
applications, many of which use viscoelastic non-Newtonian fluid. This study numerically …
