Stage Chimie Rhône entre janvier et juin 2024 de 5 à 6 mois
IFP Energies nouvelles (IFPEN) est un acteur majeur de la recherche et de la formation dans les domaines de l’énergie, du transport et de l’environnement. De la recherche à l’industrie, l’innovation technologique est au cœur de son action, articulée autour de quatre priorités stratégiques : Mobilité Durable, Energies Nouvelles, Climat / Environnement / Economie circulaire et Hydrocarbures Responsables.
Dans le cadre de la mission d’intérêt général confiée par les pouvoirs publics, IFPEN concentre ses efforts sur :
Partie intégrante d’IFPEN, l’école d’ingénieurs IFP School prépare les générations futures à relever ces défis.
Moving toward less carbonated transportation is a challenge for the society. It relies on the electrification of the vehicle fleet, for which batteries performance needs to be better mastered and optimized. In order to meet this ambition, representative modelling tools able to help develop and design effective processes need to be developed.
The internship subject concerns the step of cathode active material precursors (pCAM) synthesis which is commonly achieved through coprecipitation within mixed reactors. Since the thermodynamics and kinetics of the reactions are very fast, the hydrodynamic parameters (ex. mixing) play an important role in determining the quality of the obtained powder.
a coupled CFD model (thermodynamics, reactions, hydrodynamics, and population balance) is available but its use for design optimization is limited because of the sophistication of the models implemented especially the one for micro-mixing.
The aim of the internship will be to provide a comparative CFD study of several micro-mixing models available in literature to select one that is both representative of the micro-mixing in stirred reactor and reasonably demanding on computational resources.
The work will be divided into several work tasks:
Fluid mechanics, CFD (Computational Fluid Dynamics), chemical engineering, modelling skills
