CEA recherche un stagiaire ingénieur pour calibrer des modèles 3D multiphysiques SOEC avec COMSOL. Vous appliquerez des stratégies OED et analytiques pour optimiser l’identifiabilité des paramètres, en manipulant des régimes opératoires et en générant des données expérimentales pertinentes.
Le stage, basé à Grenoble, combine modélisation numérique avancée, analyse des données et visualisation des résultats, avec une supervision scientifique et des perspectives d’approfondissement dans la
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:
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.
