Local transient rheological behavior of concentrated suspensions [PDF]

open access: yes, 2011
This paper reports experiments on the shear transient response of concentrated non-Brownian suspensions. The shear viscosity of the suspensions is measured using a wide-gap Couette rheometer equipped with a Particle Image Velocimetry (PIV) device that ...

To Study the Viscosity Index of SN500 and SN150 Base Oil with Vegetable Oil and Selective Polymers as Additives [PDF]

open access: yesEngineering and Technology Journal, 2013
Viscosity index is one of the most important parameter for the lubricating oils performance. The effect of additives on the viscosity index for mineral lubricating oils SN500 and SN150 have been studied by adding castor oil, olive oil, corn oil ...

Simulation of relaxation time and storage modulus for carbon nanotubes-based nanocomposites

open access: yesJournal of Materials Research and Technology, 2021
This paper develops two equations for relaxation time and storage modulus of biopolymer nanocomposites at unlike frequency ranges. The relaxation time is correlated to zero complex viscosity, yield stress, K constant and power-law index. In addition, the

Inflation in Terms of a Viscous van der Waals Coupled Fluid [PDF]

open access: yes, 2018
We propose to describe the acceleration of the universe by introducing a model of two coupled fluids. We focus on the accelerated expansion at the early stages. The inflationary expansion is described in terms of a van der Waals equation of state for the
