Discover the hidden ways air and water degrade lubricants and cause unexpected failures in manufacturing operations.

Cavitation occurs when a fluid’s pressure drops low enough to form vapor bubbles, which then violently collapse as pressure rises again—creating shockwaves powerful enough to erode metal. This ...

Inadequate lubrication, where the necessary hydrodynamic or elastohydrodynamic film is disrupted while the machine is under load, is a common cause of severe sliding wear. Factors contributing to ...

IT is now well known that the lubrication at such nominal line contacts as are found in roller races and between gear teeth is hydrodynamic in character. It is also known that this lubrication ...

As strong oxidizers, OH radicals are crucial for water treatment applications involving plasma–liquid interactions. Hydrodynamic cavitation-based systems show promise for disinfection and ...

It is essential to valorize waste biomass and promote a circular economy for realizing sustainability and decarbonization goals. In this review, we specifically focus on anaerobic digestion (AD) ...

The lumped-parameter numerical pressure-flow model of the axial piston pump and the lubrication model of the slipper-swashplate interface have been developed. These models consider the pressure of ...

The best vaginal moisturizers have a pH similar to the vagina’s natural range. Discover expert-recommended creams, gels, suppositories, and oils for the vagina and vulva.

For transabdominal histotripsy in vivo, however, cavitation-based aberration correction (AC) is complicated by acoustic signal clutter and respiratory motion. This study develops a method that enables ...

ABSTRACT Aerator systems promote additional insertion of air into the flow and can reduce the risk of cavitation and consequent damage to hydraulic structures. This work analyzes the hydrodynamic ...
