RISUnsteady 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 ...
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 ...
