Drop Formation in Non-Newtonian Fluids [PDF]

Physical Review Letters, 2013
We study the pinch-off dynamics of droplets of yield stress and shear thinning fluids. To separate the two non-Newtonian effects, we use a yield stress material for which the yield stress can be tuned without changing the shear thinning behavior, and a shear thinning system (without a yield stress) for which the shear thinning can be controlled over a ...

Analytical and Computational Modeling of Relaxation Times for Non-Newtonian Fluids

Fluids
With the availability of efficient and sophisticated finite element analysis (FEA) and computational fluid dynamics (CFD) tools, engineering designs are becoming more software-driven and simulation-based.

Comparative Study of the Performance Characteristics of Annular Jet Pumps Conveying Newtonian and Shear-Thinning Non-Newtonian Fluids

Fluids
This study investigates the factors influencing the performance characteristics of annular jet pumps (AJPs) conveying non-Newtonian fluids, to enhance their suction capability for marine organisms such as jellyfish, which exhibit properties close to non ...

Applying Tiab’s direct synthesis technique to dilatant non-Newtonian/Newtonian fluids

Ingeniería e Investigación, 2011
Non-Newtonian fluids, such as polymer solutions, have been used by the oil industry for many years as fracturing agents and drilling mud. These solutions, which normally include thickened water and jelled fluids, are injected into the formation to ...

Generation of Oil Droplets in a Non-Newtonian Liquid Using a Microfluidic T-Junction

Micromachines, 2015
We have compared the formation of oil drops in Newtonian and non-Newtonian fluids in a T-junction microfluidic device. As Newtonian fluids, we used aqueous solutions of glycerol, while as non-Newtonian fluids we prepared aqueous solutions of xanthan, a ...

Time decay of solutions for compressible isentropic non-Newtonian fluids

Boundary Value Problems
In this paper, we consider the Cauchy problem of a compressible Navier–Stokes system of Eills-type non-Newtonian fluids. We investigate the time decay properties of classical solutions for the compressible non-Newtonian fluid equations. More specifically,

CFD Simulation and PIV Measurement of Local Fluid Velocity Distribution of Newtonian and Highly Shear-Thinning Fluid in an Impeller Rotational Region

Journal of Chemical Engineering of Japan
Multistage impellers are widely used in the chemical industry to enhance the mixing of shear-thinning fluids. However, the local velocity around multistage impellers has not been sufficiently investigated.

GENERALISED HERSCHEL MODEL APPLIED TO BLOOD FLOW MODELLING

TASK Quarterly, 2012
This paper introduces a new rheological model of blood as a certain generalisation of the standard Herschel-Bulkley model (Herschel W H and Bulkley R 1926 Kolloid-Zeitschrift 39 (4) 291).
