Multivariate Sensitivity Analysis of Electric Machine Efficiency Maps and Profiles Under Design Uncertainty
Aylar Partovizadeh, Sebastian Schöps, Dimitrios Loukrezis
This work introduces the use of multivariate global sensitivity analysis for assessing the impact of uncertain electric machine design parameters on efficiency maps and profiles. C…
Maximum-Projection-Based Bayesian Optimization Utilizing Sensitivity Analysis for High-Efficiency Radial Turbine Design with Scarce Data
Eric Diehl, Adem Tosun, Dimitrios Loukrezis
We propose a data-efficient workflow to optimize the efficiency of a radial turbine design under a strict budget of high-fidelity computational fluid dynamics simulations. Assuming…
Conformalized Polynomial Chaos Expansion for Uncertainty-aware Surrogate Modeling
Dimitrios Loukrezis, Dimitris G. Giovanis
This work introduces a method to equip data-driven polynomial chaos expansion surrogate models with intervals that quantify the predictive uncertainty of the surrogate. To that end…
