Pressure Model Study on Synchronous Grouting in Shield Tunnels Considering the Temporal Variation in Grout Viscosity

open access: yesApplied Sciences, 2023
The grout pressure in the shield tunnel tail void during synchronous grouting is the key to controlling ground settlement and restraining the segment. However, the circumferential, longitudinal, and radial distribution of grout pressure considering the ...

An Equation for Variation of Viscosity with Temperature

open access: yes, 1978
Department of Physics Guru Nanak Dev University, Amritsar, (India) Manuscript received 17 October 1977, accepted 11 April 1978 A modified equation representing the variation of viscosity with temperature over high as well as low temperature regions has been suggested. Calculations have been done for Aniline and Chlorobenzene.

Total variation and error estimates for spectral viscosity approximations [PDF]

open access: yesMathematics of Computation, 1993
We study the behavior of spectral viscosity approximations to non-linear scalar conservation laws. We show how the spectral viscosity method compromises between the total-variation bounded viscosity approximations— which are restricted to first-order accuracy—and the spectrally accurate, yet unstable, Fourier method. In particular,

Influence of Cluster Formation: Viscosity of Concentrated Emulsions

open access: yesApplied Rheology, 2003
Recently a new theory of viscosity of concentrated emulsions dependency on volume fraction of droplets (Starov V, Zhdanov G: J. Colloid Interface Sci, 258, 404 (2003)) has been suggested that relates the viscosity of concentrated emulsions to formation ...

Assessing White Wine Viscosity Variation Using Polarized Laser Speckle: A Promising Alternative to Wine Sensory Analysis. [PDF]

open access: yesSensors (Basel), 2017
In this paper, we report measurements of wine viscosity, correlated to polarized laser speckle results. Experiments were performed on white wine samples produced with a single grape variety.

Prediction and Property Characterization of Injection Machining Parts Using Analysis for Relationship between Melt-Filling Pressure Measurement and Calculation Viscosity Index

open access: yesEngineering Proceedings, 2023
We examine the effects of different process parameter settings on variations in melt-filling pressure, viscosity index, and part weight based on the use of real-time pressure sensor readings of the inside of the injection melt flow path.

Spatiotemporal Variation of Mantle Viscosity and the Presence of Cratonic Mantle Inferred From 8 Years of Postseismic Deformation Following the 2010 Maule, Chile, Earthquake

open access: yesGeochemistry, Geophysics, Geosystems, 2018
Postseismic displacements following great subduction earthquakes show significant long‐wavelength and time‐dependent patterns caused primarily by transient viscoelastic relaxation processes occurring broadly at depth.
