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 ...

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

Linear Stability of Magneto Viscoelastic Walter’s B′ Type with Heat and Mass Transfer
Advances in High Energy Physics, 2022 In this paper, the couple influence of axial magnetic field and the heat and mass transfer on two rotating cylinders of Walter’s B′ viscoelastic fluids by using the potential flow theory of viscoelastic fluid has been investigated. The normal mode method

Experimental Resonances in Viscoelastic Microfluidics
Frontiers in Physics, 2021 Pulsatile flows of viscoelastic fluids are very important for lab-on-a-chip devices, because most biofluids have viscoelastic character and respond distinctively to different periodic forcing.

Flow of Viscoelastic Fluid through a Helical Coil [PDF]
Chemical and Biochemical Engineering Quarterly, 2017 The study aims at quantifying the effect of fluid elasticity on frictional pressure drop for the flow of viscoelastic fluid through a helical coil. Aqueous solutions of polyacrylamide (PAA) in the concentration range 0.25 %–0.5 % (wt/vol.) were used as ...
