RISExperimental Investigation of Aerostatic Journal Bearings Made of Carbon Fiber-Reinforced Carbon Composites
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study describes experimental results using carbon fiber-reinforced carbon (C/C) material for porous journal bearings under static conditions. Exerted radial forces of up to 90 N, a supply pressure of up to 6 bar, and ...
A Novel Method to Achieve Fast Multi-Objective Optimization of Hydrostatic Porous Journal Bearings Used in Hydraulic Turbomachine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The hydrostatic journal bearing equipped with a carbon-fiber-reinforced carbon-based porous bushing is employed in the hydraulic turbomachine. The bearing exhibits high load capacity, but may unduly consume pressurized ...
An Improved One-Dimensional Flow Model for Side Chambers of Centrifugal Pumps Considering the Blade Slip Factor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The blade slip factor significantly influences the prediction accuracy of the self-closure one-dimensional flow model for side chambers of centrifugal pumps. Wiesner's and Stodola's slip factors, which are used to formulate ...
A Pressure Model for Open Rotor–Stator Cavities: An Application to an Adjustable-Speed Centrifugal Pump With Experimental Validation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: For a centrifugal pump, the interaction between the leakage and the pressure profile in the side chambers is crucial to the performance and reliability of the pump. However, existing theoretical models for directly predicting ...
