VISCOMETRY OF NANODISPERSE MAGNETIC LIQUIDS AND LUBRICATING OILS. 2. METROLOGICAL ANALYSIS OF A DEVICE FOR RHEOLOGICAL STUDIES OF MAGNETIC NANODISPERSE LIQUID MEDIA

Физико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2021
An analysis is carried out of the main sources of methodological errors of the magnetic rotary viscometer. The analysis allowed to improve design and to eliminate critical modes of the research.

Rheological measurements of large particles in high shear rate flows [PDF]

, 2012
This paper presents experimental measurements of the rheological behavior of liquid-solid mixtures at moderate Stokes and Reynolds numbers. The experiments were performed in a coaxial rheometer that was designed to minimize the effects of secondary flows.

Shear Stress Measurements of Non-Spherical Particles in High Shear Rate Flows [PDF]

, 2008
The behavior of liquid-solid flows varies greatly depending on fluid viscosity; particle and liquid inertia; and collisions and near-collisions between particles. Shear stress measurements were made in a coaxial rheometer with a height to gap ratio (b/r0)

The connection between shear and star formation in spiral galaxies

, 2005
We present a sample of 33 galaxies for which we have calculated (i) the average rate of shear from publish rotation curves, (ii) the far-infrared luminosity from IRAS fluxes and (iii) The K-band luminosity from 2MASS.

Rheology of Lamellar Liquid Crystals in Two and Three Dimensions: A Simulation Study

, 2012
We present large scale computer simulations of the nonlinear bulk rheology of lamellar phases (smectic liquid crystals) at moderate to large values of the shear rate (Peclet numbers 10-100), in both two and three dimensions.

Whole Blood Viscosity Reference Intervals and Its Correlation with Hematology and Serum Chemistry in Cats Using Scanning Capillary Method

Animals, 2023
Whole blood viscosity, a hemorheological factor, is currently used for diagnosis, as it is correlated with various vascular diseases that are difficult to diagnose early with a general blood test.

Enhancement of small-scale turbulent dynamo by large-scale shear

, 2017
Small-scale dynamos are ubiquitous in a broad range of turbulent flows with large-scale shear, ranging from solar and galactic magnetism to accretion disks, cosmology and structure formation.

Molecular dynamics simulations of oscillatory Couette flows with slip boundary conditions [PDF]

, 2012
The effect of interfacial slip on steady-state and time-periodic flows of monatomic liquids is investigated using non-equilibrium molecular dynamics simulations.

Preliminary Study on The Utilization Of Seaweed and Green Grass Jelly Leaves as Candidate Alternatives for EOR Polymer

Teknik, 2020
The declining in production can occur because wells that have been producing for a long time are no longer able to lift oil to the surface in primary and secondary ways.

Experimental Study on Flocculation Effect of Tangential Velocity in a Cone-Plate Clarifier

Separations, 2021
A large number of particles with small size and light density in mine water are difficult to remove by traditional separation equipment. In order to improve the efficiency of mine water treatment, a cone-plate clarifier is proposed in this paper.
