Particle Separation in a Microchannel with a T-Shaped Cross-Section Using Co-Flow of Newtonian and Viscoelastic Fluids [PDF]
Micromachines, 2023 In this study, we investigated the particle separation phenomenon in a microchannel with a T-shaped cross-section, a unique design detailed in our previous study. Utilizing a co-flow system within this T-shaped microchannel, we examined two types of flow

A simple yet efficient approach for electrokinetic mixing of viscoelastic fluids in a straight microchannel [PDF]
Scientific Reports, 2022 Many complex fluids such as emulsions, suspensions, biofluids, etc., are routinely encountered in many micro and nanoscale systems. These fluids exhibit non-Newtonian viscoelastic behaviour instead of showing simple Newtonian one.

pH-Responsive Viscoelastic Fluids of a C22-Tailed Surfactant Induced by Trivalent Metal Ions [PDF]
Molecules, 2023 pH-responsive viscoelastic fluids are often achieved by adding hydrotropes into surfactant solutions. However, the use of metal salts to prepare pH-responsive viscoelastic fluids has been less documented.

Electro-Elastic Instability and Turbulence in Electro-osmotic Flows of Viscoelastic Fluids: Current Status and Future Directions [PDF]
MicromachinesThe addition of even minute amounts of solid polymers, measured in parts per million (ppm), into a simple Newtonian fluid like water significantly alters the flow behavior of the resulting polymer solutions due to the introduction of fluid ...

Sheathless Microflow Cytometry Using Viscoelastic Fluids. [PDF]
Sci Rep, 2017 AbstractMicroflow cytometry is a powerful technique for characterization of particles suspended in a solution. In this work, we present a microflow cytometer based on viscoelastic focusing. 3D single-line focusing of microparticles was achieved in a straight capillary using viscoelastic focusing which alleviated the need for sheath flow or any other ...

Microswimming in viscoelastic fluids
Journal of Non-Newtonian Fluid Mechanics, 2021 The locomotion of microorganisms and spermatozoa in complex viscoelastic fluids is of critical importance in many biological processes such as fertilization, infection, and biofilm formation. Depending on their propulsion mechanisms, microswimmers display various responses to a complex fluid environment: increasing or decreasing their swimming speed ...

Lattice Boltzmann method for viscoelastic fluids
Physical Review E, 2001 Lattice Boltzmann model for viscoelastic flow simulation is proposed; elastic effects are taken into account in the framework of Maxwell model. The following three examples are studied using the proposed approach: a transverse velocity autocorrelation ...

Observation of a backward sliding motion for rollers on surfaces in viscoelastic fluid [PDF]
Nature CommunicationsWhen wheels roll on the ground, they move forward via the contact friction. This propulsion mechanism is also frequently used to create artificial microswimmers in viscous liquid environment.

RELATIVISTIC VISCOELASTIC FLUID MECHANICS [PDF]
International Journal of Modern Physics: Conference Series, 2011 We explain the relativistic theory of viscoelasticity which we have recently constructed on the basis of Onsager's linear nonequilibrium thermodynamics. This theory universally reduces to the standard relativistic Navier-Stokes fluid mechanics in the long time limit. Since effects of elasticity are taken into account, the dynamics at short time scales
