RISRotordynamic Characteristics Prediction for Hole-Pattern Seals Using Computational Fluid Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The experimental setup for a hole-pattern seal is modeled using computational fluid dynamics (CFD) and results compared with measured test data and bulk flow model (ISOTSEAL) predictions. The inlet swirl boundary condition ...
Metal Temperature Correlations in Tilting Pad Journal Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The predicted and measured bearing metal temperatures of tiltingpad journal bearings are examined. All bearings are a fivepad design with loadbetweenpad orientation. The two loaded pads in each bearing are instrumented ...
Rotordynamic Characteristics for a Tooth-On-Rotor Long Labyrinth Seal Using Computational Fluid Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. The paper compares experimentally derived dynamic force coefficients for a tooth on rotor (TOR) labyrinth seal (LS) against predictions obtained from URANS (Unsteady Reynolds Averaged Navier–Stokes) computational ...
Effect of Pad Material, Copper Versus Steel, on the Performance of a Tilting Pad Journal Bearing: Measurements and Predictions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: High-temperature operation limits the life of fluid film bearings
On the Effect of Supplied Flow Rate to the Performance of a Tilting-Pad Journal Bearing—Static Load and Dynamic Force Measurements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Rotating machinery relies on engineered tilting-pad journal bearings (TPJB) to provide static load support with minimal drag power losses, safe pad temperatures, and ensuring a rotor-dynamic stable rotor operation. End ...
