RISGenetic Integration of Different Diagnosis Methods and/or Fault Features for Improvement of Diagnosis Accuracy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Genetic integration of different diagnosis methods and/or fault features is proposed in this paper for improvement of diagnosis accuracy, and a weighted matrix is established by integrating neural ...
Performance Analysis of Oil Lubricated Foil Bearing With Flexible Supported Back Spring Structure—Part I: Model Development and Numerical Investigation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new type of multileaf oil lubricated foil bearing with flexible supported back spring structure was proposed to satisfy the requirement of high rotating velocity for turbo pump, where the rotor was submerged in the ...
A Numerical Study on the Effect of Bleed System on Starting Ability and Flow Performance of Rampressor Inlet
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A unique supersonic compressor rotor with high pressure ratio, termed the Rampressor, is presented by Ramgen Power Systems, Inc., (RPS). Based on the models of Rampressor inlet, the inlet flow field with bleed system is ...

Abstract: As described in Part I (Zhang et al., “Performance Analysis of Oil Lubricated Foil Bearing With Flexible Supported Back Spring Structure—Part I: Model Development and Numerical Investigationâ€, ASME J. Eng. Gas Turbines ...
Endwall Film Cooling Performance for a First-Stage Guide Vane With Upstream Combustor Walls and Inlet Injection
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Effects of an upstream combustor wall on turbine nozzle endwall film cooling performance are numerically examined in a linear cascade in this paper. Film cooling is by two rows of cooling holes at 20% of the axial chord ...
Comparisons of Endwall Overall Effectiveness From Two Film Hole Distribution Patterns at Low and High Exit Mach Numbers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, detailed overall cooling effectiveness and associated flow patterns are presented for two distinct film hole distribution patterns over a turbine endwall: an axial-row pattern and an iso-Mach number line row ...
