Mechanistic Investigation of Microdroplet Formation in High-Viscosity Shear-Thinning Hydrogel Bioinks. [PDF]

Gels
High-resolution biofabrication requires precise microscale deposition, yet drop-on-demand (DOD) inkjet bioprinting is constrained by a narrow printable viscosity window.

Swimming efficiency in a shear-thinning fluid [PDF]

Physical Review E, 2017
Micro-organisms expend energy moving through complex media. While propulsion speed is an important property of locomotion, efficiency is another factor that may determine the swimming gait adopted by a micro-organism in order to locomote in an ...

Bulk and Interfacial Shear Thinning of Immiscible Polymers [PDF]

Physical Review E, 2001
Nonequilibrium molecular dynamics simulations are used to study the shear thinning behavior of immiscible symmetric polymer blends. The phase separated polymers are subjected to a simple shear flow imposed by moving a wall parallel to the fluid-fluid ...

Maximum spreading of impacting shear-thinning and shear-thickening drops. [PDF]

Proc Natl Acad Sci U S A
The maximum spreading of an impacting liquid drop is a key metric for characterizing the fundamental fluid process of drop impact. While extensively studied for Newtonian liquids, how far a non-Newtonian drop can spread upon impacting a solid substrate remains an open question.

Particle settling in a shear-thinning, viscoelastic fluid in the presence of wall effects. [PDF]

Sci Rep
The settling of particles in fluids is a widespread phenomenon and commonly involves accounting for the effects of walls. Particle settling and wall effects are well understood for Newtonian fluids but the consequences of non-Newtonian fluid properties ...

Shear thinning in dilute polymer solutions

The Journal of Chemical Physics, 2006
We use bead-spring models for a polymer coupled to a solvent described by multiparticle collision dynamics to investigate shear thinning effects in dilute polymer solutions. First, we consider the polymer motion and configuration in a shear flow. For flexible polymer models we find a sharp increase in the polymer radius of gyration and the fluctuations

Active turbulence in shear-thinning fluid

Physical Review Research
The study of active matter system has critical importance in revealing the physical essence of biological collective behavior. Dense bacterial suspension—a typical biological active matter, exhibits a wide range of phenomenona, among which bacterial turbulence has received extensive interest in recent years.

The Rheology behavior of Aramid and Cellulose Nanowhisker Suspensions [PDF]

Journal of Chemical and Petroleum Engineering, 2022
The flow responses of aramid and cellulose nanowhisker (fibrids) or CNCs (cellulose nanocrystal) suspended in a sulfuric acid and water respect at loadings of about 17% weight fraction was determined in transient shear flow. The effect of temperature and

Numerical simulations of blood cell flow in non-Newtonian fluid [PDF]

MATEC Web of Conferences, 2020
We investigated how non-Newtonian viscosity behavior affects the flow characteristics of blood cells. Our findings offer insight about how shear thinning affects the dispersion of liposome-encapsulated hemoglobin and red blood cells in blood. The lattice
