RISSurrogate Model Development for Air Foil Thrust Bearings With Chevron-Patterned Trailing Edge1
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Air foil thrust bearings provide some advantages over oil-lubricated thrust bearings. The use of these bearings reduces weight and increases dynamic stability, making it possible to reach high rotational speeds. However, ...
Effects of Tire Attributes on the Aerodynamic Performance of a Generic Car–Tire Assembly1
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of tires on the overall aerodynamic drag in a car–tire assembly has been studied and deemed considerable from past studies. It has been shown that it is important to understand how the vehicle body and the tires ...
A Study of the Effect of Various Recess Shapes on Hybrid Journal Bearing Performance Using Computational Fluid Dynamics and Response Surface Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Hybrid bearings are mostly used in high-speed and load situations due to their better stability and loading capacity. They are typically designed with recess grooves to enhance both static and dynamic performance of the ...
Effect of Recess Shape on the Performance of a High-Speed Hybrid Journal Bearing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Hybrid bearings are getting more and more attention because of their ability to provide both hydrodynamic support for high-speed rotors and hydrostatic lift in low-speed conditions such as during startup. Hybrid bearings ...
An Optimum Design Approach for Textured Thrust Bearing With Elliptical-Shape Dimples Using Computational Fluid Dynamics and Design of Experiments Including Cavitation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Textured thrust bearings are capable of providing higher load capacity and lower friction torque compared to nontextured bearings. However, most previous optimization efforts for texturing geometry were focused on rectangular ...
The Influence of Surface Patterning on the Thermal Properties of Textured Thrust Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Contact performance can be enhanced by using textured surfaces. These are also found to have influences on lubricated contacts. A procedure to find the optimal partially textured thrust bearing configuration is presented ...
Elliptical Shape Hole-Pattern Seals Performance Evaluation Using Design of Experiments Technique1
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Hole-pattern annular gas seals have two distinct flow regions: an annular jet-flow region between the rotor and stator, and cylindrical indentions in the stator that serve as cavities where flow recirculation occurs. As ...
Hemodynamics Characteristics of a Four-Way Right-Atrium Bypass Connector
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Currently, the surgical procedure followed by the majority of cardiac surgeons to address right ventricular dysfunction is the Fontan procedure, which connects the superior vena cava and inferior vena cava (IVC) directly ...
