Abstract: Abstract. As supercritical carbon dioxide (S-CO2) Brayton cycles advance toward higher power densities, the lubrication and dynamic characteristics of support bearings are critical to the stability of turbine rotor systems. ...

Abstract: Durability is a major concern with concrete structures. The ion transport properties of concrete cover can greatly influence the durability of concrete structures since most of the deterioration starts from the surface. ...

Abstract: This study investigates the film formation mechanism of lubrication using a small quantity of lubricating medium in a water environment. A roller-on-disc test rig combined with a fluorescent technique is employed to directly ...

Abstract: Abstract. This study focuses on the film-forming characteristics of the secondary lubricating medium in a water environment under different working conditions, and the roller-on-disc lubrication film test rig, along with ...

Abstract: Previous research has revealed that introducing a secondary lubricating medium can temporarily enhance water-lubricated bearing performance, thereby reducing the risk of lubrication failure under challenging conditions. ...
