Shear viscosity of inhomogeneous fluids

The Journal of Chemical Physics, 2012
Using molecular dynamics simulations on inhomogeneous fluids, we have studied the effects of strong density inhomogeneities of varying wavelengths on the shear viscosity computed locally. For dense fluids, the local average density model combined with an adequate weight function yields a good description of the viscosity profiles obtained by ...

Influence of the Carrier Fluid Viscosity on the Rotational and Oscillatory Rheological Properties of Ferrofluids.

Journal of Nanoscience and Nanotechnology, 2019
This work mainly presents a comprehensive experimental study on the magnetorheological behavior of ferrofluids with carrier fluids of different viscosities.

MEMS fluid viscosity sensor

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2010
Quartz shear resonators are employed widely as sensors to measure Newtonian viscosities of liquids. Perturbation of the electrical equivalent circuit parameters of the plate resonator by the fluid loading permits calculation of the mass density-shear viscosity product.

Extensional Viscosity Measurements for Low‐Viscosity Fluids

Journal of Rheology, 1987
A design for an extensional viscometer is described which is useful for studying low‐viscosity fluids at high strain rates. The configuration consists of opposing nozzles through which the liquid is either sucked in or blown out. Measurement of the force required to keep the nozzles at a fixed distance apart as a function of flow rate directly yields a

Fluid viscosity nanosensor

2010 IEEE Sensors Applications Symposium (SAS), 2010
Quartz shear resonators are employed widely as sensors to measure Newtonian viscosities of liquids. Perturbation of the electrical equivalent circuit parameters of the plate resonator by the fluid loading permits calculation only of the mass density - shear viscosity product.

Oral Sensory Discrimination of Fluid Viscosity

Dysphagia, 1997
This study was designed to investigate the ability of normal young adult volunteers to sensorially identify Newtonian fluids of specified viscosities. Twenty subjects, 10 men and 10 women between the ages of 18 and 29 years participated. Seven stimuli, consisting of combinations of corn syrup and water, with viscosities ranging from 2 to 2,240 ...

Critical viscosity exponent for classical fluids

Physical Review E, 2005
A self-consistent mode-coupling calculation of the critical viscosity exponent z(eta) for classical fluids is performed by including the memory effect and the vertex corrections. The incorporation of the memory effect is through a self-consistency procedure that evaluates the order parameter and shear momentum relaxation rates at nonzero frequencies ...

The Effective Viscosity of Polar Fluids

Transactions of the Society of Rheology, 1970
The effective viscosity of a polar fluid is a measure of the amount of traditional shear viscosity the polar fluid will appear to possess in a particular flow situation. Four classical flow configurations are considered here; Couette flow, plane Poiseuille flow, pipe flow, and flow between concentric rotating cylinders.

Photoinduced Reversible Change of Fluid Viscosity

Journal of the American Chemical Society, 2005
We report a reversible photoinduced fluid viscosity change. A small amount of a "photoswitchable" azobenzene-modified cationic surfactant (4-butylazobenzene-4'-(oxyethyl)trimethylammonium bromide, AZTMA) was added to a wormlike micellar solution of cetyltrimethylammonium bromide (CTAB) containing sodium salicylate (NaSal).
