Viscous Cosmology for Early- and Late-Time Universe [PDF]

, 2017
From a hydrodynamicist's point of view the inclusion of viscosity concepts in the macroscopic theory of the cosmic fluid would appear most natural, as an ideal fluid is after all an abstraction (excluding special cases such as superconductivity).

Effects of Mixing Ratio of Binary Fine Particles on the Packing Density and Filtration Characteristics

KONA Powder and Particle Journal, 2015
Binary fine particles were dispersed in glycerol aqueous solutions with different mixing ratios to study the effects of particle size distribution and fluid viscosity on the cake properties in dead-end filtration, such as average porosity, average ...

Analysis of the effects of drilling fluid viscosity on hole cleaning in directional well drilling [PDF]

International Journal of Mining and Geo-Engineering
Hole cleaning is one of the most important aspects of extractive drilling operations. When drill cuttings combine with drilling fluids, cutting bed gel is created, which becomes extremely challenging to remove while drilling.

Heat and fluid flow in a scraped-surface heat exchanger containing a fluid with temperature-dependent viscosity [PDF]

, 2010
Scraped-surface heat exchangers (SSHEs) are extensively used in a wide variety of industrial settings where the continuous processing of fluids and fluid-like materials is involved.

Viscosity of Equine Synovial Fluid [PDF]

Acta Veterinaria Scandinavica, 1976
Synovial fluid samples from 51 light horses were examined with respect to their rheologie properties. The analyses were made with a Rotovisco RV3 rotational viscosimeter. Samples from carpal, stifle and hock joints and from healthy joints, joints with synovitis and joints with infectious arthritis were studied.

A Study to Investigate the Viscosity Effect on Micro-Confined Fluids Flow in Tight Formations Considering Fluid–Solid Interaction

Frontiers in Earth Science, 2021
Understanding different fluids flow behavior confined in microscales has tremendous significance in the development of tight oil reservoirs. In this article, a novel semiempirical model for different confined fluid flow based on the concept of boundary ...

Effects of fluid influx, fluid viscosity, and fluid density on fluid migration in the mantle wedge and their implications for hydrous melting

Geosphere, 2018
The migration pathways of hydrous fluids in the mantle wedge are influenced by the compaction of the porous mantle matrix, which depends on the matrix permeability, fluid viscosity, and fluid density.

A critical review on fundamental mechanisms of spontaneous imbibition and the impact of boundary condition, fluid viscosity and wettability

, 2017
Spontaneous imbibition (SI) is one of the primary mechanisms of oil production from matrix system in fractured reservoirs. The main driving force for SI is capillary pressure. Researches relating to SI are moving fast.
