Flame Spray Pyrolysis (FSP) Digital Twin Development for Nanoparticles synthesis (Collaboration with CNRS/Central-Supélec)

Leader: Yann Leconte

Flame Spray Pyrolysis (FSP) processes, commonly used in industry for the large-scale production of nanoparticles, allow for the low-cost, one-step synthesis of nanopowders through the decomposition of a precursor in a combustion flame. These processes are the subject of intense R&D activity to synthesize nanostructures with more complex morphologies. However, these developments, carried out using empirical approaches, require numerous syntheses and are time-consuming.
The DIGIFLAME project aims to establish the first models for developing a digital twin of FSP, with the aim of ultimately conducting in silico experiments and thus reducing the number of “real” tests before developing a material. These digital syntheses will make it possible to test the theories governing the formation of a given morphology and to optimize synthesis parameters. The model material selected for this study is iron oxide.

To achieve this, the project will benefit from the recognized expertise of the EM2C laboratory (CNRS, CentraleSupélec, Université Paris-Saclay) in the simulation of turbulent flames and in the formation of nanoparticles in these flames. The project will also benefit, for the experimental aspect necessary for the validation of predictions, from the FSP platform set up at LEEL (DRF/IRAMIS/NIMBE) as part of the PEPR Diadem. These two laboratories will co-supervise a thesis on the subject.
