Rheological properties of hydroxypropylmethyl cellulose/sodium dodecylsulfate mixtures [PDF]

Journal of the Serbian Chemical Society, 2014
Rheological properties of mixtures of hydroxypropylmethyl cellulose (HPMC), a nonionic associative cellulose ether, and sodium dodecylsulfate (SDS), an anionic surfactant, were investigated by viscosity measurements performed at different shear rates (0 ...

Re-Entrant Corner for a White-Metzner Fluid

Fluids, 2021
Viscoelastic fluids can be difficult to model due to the wide range of different physical behaviors that polymer melts can exhibit. One such feature is the viscous elastic boundary layer.

Effect of Rheological Properties of Liquid Foods on Heat Sterilization Process in Taylor-couette Flow Apparatus

Chemical Engineering Transactions, 2019
This study numerically investigates the effect of rheological liquid foods on heat sterilization process using Taylor–Couette flow sterilizer (TCFS). As model thermal processing, the destruction of Clostridium botulinum and thiamine was selected.

Universal mechanism of shear thinning in supercooled liquids

Communications Physics
Soft glassy materials experience a significant reduction in viscosity η when subjected to shear flow, known as shear thinning. This phenomenon is characterized by a power-law scaling of η with the shear rate $$\dot{\gamma }$$ γ ° , $$\eta \propto {\dot ...

Flow and hydrodynamic shear stress inside a printing needle during biofabrication.

PLoS ONE, 2020
We present a simple but accurate algorithm to calculate the flow and shear rate profile of shear thinning fluids, as typically used in biofabrication applications, with an arbitrary viscosity-shear rate relationship in a cylindrical nozzle.

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Microstructure Reconstruction in Battery Electrodes Using Machine Learning Based on Low‐Voltage Focused Ion Beam–Scanning Electron Microscopy Tomography Images

Advanced Engineering Materials, EarlyView.
Low‐voltage FIB‐SEM tomography combined with a image preprocessing pipeline improves phase contrast and enables reliable machine‐learning segmentation of conductive networks in lithium‐ion battery electrodes. Structural descriptors are extracted from segmented images, done semimanually and automated, and compared.

An improved equivalent viscosity model for the bubbly oil under high shear rate

Friction
Shear-thinning effect of pure oil and distribution of bubble size are essential factors affecting the viscosity of bubbly oil. This study aims to establish an improved equivalent viscosity model for bubbly oil by considering the shear-thinning effect and
