RISThermohydrodynamic Analysis of Dynamic Characteristics for the Third-Generation Carbon Dioxide (CO2) Gas Foil Journal Bearings Under High Pressure and Temperature
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Nowadays, gas foil bearings (GFBs) have become a key enabling technology for S-CO2 turbomachinery applications, due to their capacity to withstand extreme operating conditions, and without pollution. Furthermore, ...
Rotor Dynamic of Bearing-Rotor System Supported by Gas Foil Bearing Under Two Housing Excitations: Random Vibration and Transient Impulse
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. As the core component of the onboard refrigeration system, the turbo cooler is used to expand and cool the hot bleed of the engine, thus providing cold air. The extremely high rotating speed of the turbo cooler ...
Leakage and Rotordynamic Characteristics for Three Types of Annular Gas Seals Operating in Supercritical CO2 Turbomachinery
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The balance piston seal in multiple-stage centrifugal compressors and axial turbines sustains the largest pressure drop through the machines and therefore plays an important role in successful full load operation at high ...
