RISImproving Tilting Pad Journal Bearing Predictions—Part II: Comparison of Measured and Predicted Rotor Pad Transfer Functions for a Rocker Pivot Tilting Pad Journal Bearing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As described in Part I (Wilkes et al., 2012, “Improving TiltingPad Journal Bearing Predictions—Part I: Model Development and Impact of Rotor Excited Versus Bearing Excited Impedance Coefficients,†ASME J. Eng. Gas ...
Improving Tilting Pad Journal Bearing Predictions—Part I: Model Development and Impact of Rotor Excited Versus Bearing Excited Impedance Coefficients
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The floatingbearingtestrig concept was initially developed by Glienicke in 1966 and has since been used to test many tiltingpad journal bearings (TPJBs). The impedances measured during these tests have been compared to ...
Impact of Bearing Clearance on Measured Stiffness and Damping Coefficients and Thermal Performance of a High-Stiffness Generation 3 Foil Journal Bearing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: High-speed foil bearings are currently used in increasingly demanding, high performance applications. The application under consideration is a 120 krpm natural gas turboexpander-compressor, which requires 38 mm (1.5 in.) ...
Experimental Validation of a Wide-Range Centrifugal Compressor Stage for Supercritical CO2 Power Cycles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Successful implementation of sCO2 power cycles requires high compressor efficiency at both the design-point and over a wide operating range in order to maximize cycle power output and maintain stable operation over a wide ...
The Comparison of Aerodynamic Performance Data Acquired From Thermal Measurements and a Torquemeter on a Compressor Impeller
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Full-thermal heat-soak of machinery is vital for acquiring accurate aerodynamic performance data, but this process often requires significant testing time to allow all facility components to reach a steady-state temperature. ...
