... performance of each sample, the impact of blade geometric deviations on compressor performance was quantified, and sensitivity analysis was conducted using Sobol' index. It was observed that the total pressure ratio was most sensitive to the stagger angle deviation at 50% blade height, while the sensitivity...

...Leonardo Urbiola-Soto A robust approach to investigate a tilting pad journal bearing (TPJB) as a whole tolerance stack-up assembly is presented. Normal component variation within actual design tolerances is considered. The vector loop is expanded via Taylor series for sensitive analysis...

Sensitivity analysis has identified important...

... for implementing the methodology is developed and a simulation model is set up. Finally, different degradation-over-time scenarios for a gas turbine are simulated and a sensitivity analysis on methodology response is carried out, to assess the capability and the reliability of the prognostic methodology...

... that the optimum nominal powers in TWC mode, OWC mode, and HDF mode are 3.5 MW, 3.4 MW, and 0.8 MW, respectively. Furthermore, in order to determine the sensitivity of results to parameters such as cost of electricity, cost of fuel, and carbon tax, a comprehensive sensitivity analysis was conducted. It is noted...

... order sensitivity analysis performed during detailed design was unable to detect a failure mode while a probabilistic analysis revealed a small yet significant risk of failure. Therefore, a secondary flow analyst does not have a justifiable reason to be highly confident of a design qualified by a first...

... earlier than expected using deterministic methods is approximately 80%. The application of a sensitivity analysis to a surrogate model for the life identified the leading drivers of the minimum combustor life and the typical combustor life as the material property variability and the circumferential...

... response and sensitivity analysis are performed. It should be noted that in many cases these approximations can be sufficiently accurate when applied in relatively small parameter variation ranges resulting from the technological imperfections and operational uncertainties discussed in the previous...

A sensitivity analysis allowed to evaluate the economic convenience of the two plants as a function of the costs of the hydrogen and electrical energy. Capital costs have been taken from literature and upscaled according to the power-law...
