Labyrinth Seal Discharge Coefficient for Rectangular Cavities

, 2009
A labyrinth seal leakage prediction equation can be developed by considering the seal as a series of orifices and cavities. CFD simulations are used to investigate the discharge coefficient’s dependence of each tooth upon the seal geometry and flow ...

Phase Diagrams Enable Solid‐State Battery Design

Advanced Materials Interfaces, EarlyView.
Batteries are non‐equilibrium devices with inherent thermodynamic driving forces to react at interfaces, regardless of kinetics or operating conditions. Chemical potential mismatches across interfaces are dissipated via interfacial reactions. In this work, it is illustrated how phase diagrams and chemical potential maps predict degradation pathways but

Discharge coefficient of vertical sluice gates with broad crested weir under free-submerged orifice flows using best subset regression

Water Science and Technology
Accurate calculation of flow discharge for sluice gates is essential in irrigation, water supply, and structure safety. The measurement of discharge with the requirement of distinguishing flow regimes is not conducive to application.

Influence of Carbon Nanoparticles on Electrically Induced Wear of Grease‐Lubricated Steels

Advanced Materials Interfaces, EarlyView.
When an electric current enters a pair of rubbing surfaces, enormous damage takes place. In this research, how such damage occurs in the presence of protective grease and the mitigation with added carbon nanoparticles, were investigated. It was discovered that those particles regulate transport and interfacial electrical stability of the grease ...
