Fluids, 2021 Viscoelastic fluids are non-Newtonian fluids that exhibit both “viscous” and “elastic” characteristics in virtue of the mechanisms used to store energy and produce entropy.

Durotaxis in viscoelastic fluids
Physical Review FluidsOrganisms often swim through fluids that are spatially inhomogeneous. If the fluids are polymeric, gradients in polymer concentration may lead to gradients in both fluid viscosity and elasticity. In this letter, we present theoretical results for the dynamics of active particles, biological or otherwise, swimming through spatially inhomogeneous ...

Active particles in geometrically confined viscoelastic fluids [PDF]
New Journal of Physics, 2019 We experimentally study the dynamics of active particles (APs) in a viscoelastic fluid under various geometrical constraints such as flat walls, spherical obstacles and cylindrical cavities.

Recent progress of particle migration in viscoelastic fluids.
Lab on a Chip, 2018 Recently, research on particle migration in non-Newtonian viscoelastic fluids has gained considerable attention. In a viscoelastic fluid, three dimensional (3D) particle focusing can be easily realized in simple channels without the need for any external

Stokes layers in oscillatory flows of viscoelastic fluids. [PDF]
Philos Trans A Math Phys Eng Sci, 2020 Oscillatory flows of viscoelastic fluids are studied from the perspective of Stokes viscoelastic layers. We identify the governing dimensionless variables, and study the flows in a general way for fluids with linear rheology.

Electrokinetic oscillatory flow and energy conversion of viscoelastic fluids in microchannels: a linear analysis [PDF]
Journal of Fluid Mechanics, 2021 We studied the electrokinetic flow of viscoelastic fluids subjected to an oscillatory pressure gradient. Under the assumption of laminar unidirectional flow, the constitutive and motion equations of fluids are in the linear regime.

Dynamic control of particle separation in deterministic lateral displacement separator with viscoelastic fluids. [PDF]
Sci Rep, 2018 We proposed an innovative method to achieve dynamic control of particle separation by employing viscoelastic fluids in deterministic lateral displacement (DLD) arrays.
