Les missions du poste
The goal of this interniship is to use numerically advanced strategies for the calibration of our 3D multiphysics COMSOL models of Solid-Oxide-Electrolyzer-Cells (SOEC). Our current SOEC models involve different coupled physical phenomena such as electrochemical, thermal, fluidics and radiative processes. These phenomena are described by dedicated physical models, whose parameters requires careful calibration against targeted experimental data. The proposed methodology will use innovative Optimal Experimental Design (OED) strategies to address parameter correlation and identifiability issues during model calibration. The method, will consider the following steps :
1. identify operating conditions for which different physical mechanisms are expected to dominate (e.g., low current --> activation losses dominate)
2. Global screening inside these regimes to reduce the number of important parameters
3. apply OED and Fisher Information Matrix (FIM) criteria to identify experimental conditions that minimize parameter correlations.
A COMSOL model of the a SOEC cell setup operating both in steady (IV-curve) and dynamical (EIS) conditions will be developed during the stage. The model will be used to numerically reproduce experimental conditions that allow maximizing the sensitivity to the different model's parameters. The student will be able to learn an advanced calibration strategy that can be applied to any complex 3D FEM model, potentially involving several multiphysics and non-linear coupling."
