Dynamic characteristics of the gear-rotor system in compressed air energy storage considering friction effects [PDF]
The tooth surface friction effects and the resulting tooth surface contact temperature are important factors for the dynamic characteristics of a gear-rotor system in compressed air energy storage (CAES).

CFD Investigation into Flow Characteristics of a Special Splash Lubrication in Light Helicopters
Lubricating oil flow characteristics are the primary concern in the main reducer of light helicopters. To improve the lubricating performance of the main reducer, a special lubrication system is innovatively constructed by adding two oil-guiding tubes to

Development of an oil-air lubrication system with a piezoelectric nozzle for machine tool spindles.
Oil-air lubrication is one of the effective lubrication methods for the high-speed spindle of machine tools. However, the oil supply rate to the bearing fluctuates remarkably due to the intermittent oil supply from the oil-air mixing valves. In this study, a new oil-air mixing equipment is developed by applying the piezoelectric nozzle which has been ...

Despite benefits to storage stability and handleability of aluminum scrap, octadecyl phosphonic acid (ODPA) SAMs reduce the tensile strength of wires produced using friction‐induced recycling. Etching and methyl diphosphonic acid (MDPA) coatings, however, have little effect.

Particle morphology controls the balance between printability and electrical connectivity in low‐temperature AgCu/Ag metallization pastes. Flake‐shaped AgCu particles form extended low‐resistance contacts, whereas spherical particles favor processability at high metal loading. Fine Ag particles further tune void filling and conductive‐network formation
