Fluids with anisotropic viscosity [PDF]
Summary: Motivated by rotating fluids, we study incompressible fluids with anisotropic viscosity. We use anisotropic spaces that enable us to prove existence theorems for less regular initial data than usual. In the case of rotating fluids, in the whole space, we prove Strichartz-type anisotropic, dispersive estimates which allow us to prove global ...

A Measured Method for In Situ Viscosity of Fluid in Porous Media by Nuclear Magnetic Resonance
At present, the existing measuring methods for viscosity of fluid can only obtain the viscosity of bulk fluid, while the in situ viscosity of fluid in porous media cannot be acquired. In this paper, with the combination of nuclear magnetic resonance (NMR)

Research on Conductivity Damage Based on Response Surface Analysis
Hydraulic fracturing is an important means of developing unconventional oil and gas layers. The fracture conductivity of tight sandstone reservoirs after fracture is affected by many factors, such as the interaction between the fracturing fluid, water ...

Numerical Analysis on the Stability of Hydraulic Fracture Propagation
The formation of dense spacing fracture network is crucial to the hydraulic fracturing treatment of unconventional reservoir. However, one difficulty for fracturing treatment is the lack of clear understanding on the nature of fracture complexity created

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

Fluid viscosity in nanochannels [PDF]
The viscosity of fluids in a nanochannel between flat plates has been investigated by molecular dynamics method. The effective viscosity coefficient was determined using the previously derived from the nonequilibrium statistical theory fluctuation-dissipation theorem.

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

Viscosity of Equine Synovial Fluid [PDF]
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.

Undulatory swimming in shear-thinning fluids: Experiments with C. elegans [PDF]
The swimming behaviour of microorganisms can be strongly influenced by the rheology of their fluid environment. In this manuscript, we experimentally investigate the effects of shear-thinning viscosity on the swimming behaviour of an undulatory swimmer ...
