This research project will be funded by ANR RAGNAROC whose final aim is to 
retrieve the temperature and concentrations of major radiating combustion 
products, i.e. carbon dioxide, water vapor, carbon monoxide and soot, by inverse 
method from hyperspectral radiative measurements. The direct application of this 
research is to improve the control of combustion processes in furnaces such as 
those used by Saint Gobain, the industrial partner of the project. One of the 
major task of the pro-ject is to develop a numerical model based on the LES and 
LBM [1] to provide high-fidelity simula-tions of sooting turbulent non-premixed 
flames representative of targeted applications. This is the objective of the 
thesis that will be co-supervised by Jean-Louis Consalvi and Pierre Boivin from 
Aix-Marseille University (jean-louis.consalvi@univ-amu.fr).

The main fundamental challenge will be to develop subgrid-scale models to 
capture the interaction between chemistry, soot production, radiation and 
turbulence [2, 3]. After a bibliographic survey and a theoretical analysis to 
develop these models, the candidate will take charge of the LBM code developed 
at the lab M2P2 for the simulation of reactive flows and will start to implement 
the mod-els. The first target flames for validation will be the laboratory-scale 
flames selected by the Interna-tional Soot Formation Workshop (ISF wokshop) [4].
