... in the literature treated the aleatory geometric imperfections as deterministic or ideal cases, which imported an uncertainty bias to life prediction. Therefore, a detailed uncertainty quantification analysis is performed to quantify the impacts of laser drilling imperfections on the endwall cooling performance...

... efficiencies and are less sensitive to uncertainties from manufacturing and wear. However, the uncertainty quantification techniques required to evaluate the robustness are computationally expensive, which limits their use in robust optimization. Multi-fidelity methods offer a promising solution to reduce...

...Zhihui Li; Francesco Montomoli; Nicola Casari; Michele Pinelli In this work, a new multifidelity (MF) uncertainty quantification (UQ) framework is presented and applied to the LS89 nozzle modified by fouling. Geometrical uncertainties significantly influence the aerodynamic performance of gas...
