Static Characteristics of High-Speed Water-Lubricated Journal Bearing Considering Turbulence and Cavitation Effects
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The water-lubricated bearings tend to be turbulent and cavitating when running at a high speed. However, the modeling of the water-lubricated bearing considering the turbulence and cavitation effects has not been studied ...
Statistical Mechanics Transport Model of Magnetic Drug Targeting in Permeable Microvessel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A transport model of magnetic drug carrier particles (MDCPs) in permeable microvessel based on statistical mechanics has been developed to investigate capture efficiency (CE) of MDCPs at the tumor position. CassonNewton ...
Comparative Study on Dynamic Characteristics of Double-Pad Inwardly and Outwardly Pumping Water-Lubricated Spiral-Groove Thrust Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The dynamic characteristics of the double-pad inwardly pumping water-lubricated spiral-groove thrust bearing (SGTB) is different from that of the outwardly pumping version, especially under a high-speed condition. However, ...
Study on Lubricating Performance of the Bubbly Oil Under High Shear Rate—Part 2: Application Study in High-Speed Bearing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper aims to investigate the lubricating performance of the bubbly oil. Due to space limitation, the work is divided into two parts. Part 1 concluded that the bubbly oil under high shear rate has a lower viscosity ...
Static Characteristics of Hybrid Water-Lubricated Herringbone Groove Journal Bearing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The hydrodynamic herringbone groove journal bearing (HGJB) performs exceptionally well at high speeds but is limited by a low load-carrying capacity, largely due to the lubrication characteristics of water. To address this ...
A Thermohydrodynamic Coupling Model of Oil Aeration Turbulent Lubrication for Journal Bearing With Interface Effect
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Oil aeration lubricant in highspeed journal bearing is composed of mixture of continuous phase liquid and discrete phase bubbles. This work establishes a thermohydrodynamic (THD) coupling model for this lubrication condition. ...
Thermohydrodynamic Analysis of High-Speed Water-Lubricated Spiral Groove Thrust Bearing Using Cavitating Flow Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A thermohydrodynamic lubrication model of turbulent cavitating flow for high-speed spiral groove thrust bearing was developed considering the effects of cavitation, turbulence, inertia, breakage, and coalescence of bubbles. ...
