RISExploratory Factor Analysis for Machining Error Data of Compressor Blades Based on Dimensionality-Reduced Statistical Analysis Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Various machining errors inevitably occur on aero-engine compressor blades, including leading-edge contour error, trailing-edge contour error, camber contour error, and more. The current complexity surrounding the numerous ...
Unsteady Investigation on Tip Flow Field and Rotating Stall in Counter Rotating Axial Compressor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Contrarotating axial compressor/fan (CRAC) is a promising technology to meet the future goals aircraft industry. Massive time accurate simulations are performed to investigate rotating stall in CRAC containing two ...
Evaluating Metropolitan Flood Coping Capabilities under Heavy Storms
Publisher: American Society of Civil Engineers
Abstract: A large city surrounded by mountains like Hong Kong is susceptible to both flash floods in midmountain areas and local flooding in low-lying areas when a large rainstorm occurs. Severe rainstorms tend to be more frequent ...
A Preconditioner-Based Data-Driven Polynomial Expansion Method: Application to Compressor Blade With Leading Edge Uncertainty
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In engineering practice, the amount of measured data is often scarce and limited, posing a challenge in uncertainty quantification (UQ) and propagation. Data-driven polynomial chaos (DDPC) is an effective way to tackle ...
