Bulk viscosity of spin-one color superconductors [PDF]

, 2009
The bulk viscosity of several quark matter phases is calculated. It is found that the effect of color superconductivity is not trivial, it may suppress, or enhance the bulk viscosity depending on the critical temperature and the temperature at which the ...

When Does Eddy Viscosity Damp Subfilter Scales Sufficiently? [PDF]

, 2011
Large eddy simulation (LES) seeks to predict the dynamics of spatially filtered turbulent flows. The very essence is that the LES-solution contains only scales of size ≥Δ, where Δ denotes some user-chosen length scale. This property enables us to perform

High‐Resolution Corrosion Fingerprinting of Alloy Libraries via Microdroplet Spectroelectrochemistry

Advanced Engineering Materials, EarlyView.
Ionic‐liquid microdroplet spectroelectrochemistry enables stable, localized electrochemical measurements over extended timescales. By coupling impedance spectroscopy, wetting analysis, finite‐element simulations, and operando Raman spectroscopy, it disentangles geometrical and electrochemical effects, opening new opportunities for rapid corrosion ...

Influencing Mechanisms of Unavoidable Ions Ca2+、Mg2+ on the Viscosity of Kaolin

Kuangchan zonghe liyong
Viscosity is an important factor affecting the high-value application of kaolin. In order to figure out how unavoidable ions influence the viscosity of kaolin, the slurry was investigated through a viscomete runder different concentrations of Ca2+ and ...

Viscosity of Cu-Zn alloys [PDF]

Metalurgija, 2011
One of the basic parameters that characterize a liquid phase is its viscosity. In the paper, the results of viscosity measurements for copper, copper-zinc alloys with 5 %wt. Zn and 10 %wt.

Impact of MgO Additions on the Oxidation Resistance and Compression Behavior of Vanadium Alloys

Advanced Engineering Materials, EarlyView.
An increase in oxidation resistance at 600 °C is achieved for alloys containing more than 2.5 wt.% MgO. It has been established that, along with V2O5, MgO6V2, and Mg2O7V2 are formed, which are presumed to enhance oxidative stability. Furthermore, the possible transformation of Mg‐vanadates through reaction with CO2, which presumably occurs in this ...

Integration of OpenCV‐Based Microscopic Adhesive Volume Measurement Into a Pyiron Workflow for Automated Data Analysis

Advanced Engineering Materials, EarlyView.
Residual adhesive after electrode loading in adhesive‐assisted resistance spot welding is quantified through a traceable experimental‐to‐digital workflow. Chromatic confocal topography provides calibrated surface‐height data, while OpenCV detects the electrode imprint and integrates adhesive height into comparable volume metrics.
