Project title: Large Eddy Simulations of premixed and non-premixed flameless combustion with detailed kinetic mechanisms

Objectives. lAlthough flameless combustion is a promising solution to strongly reduce the formation of pollutant species, the non-linear interaction between chemical reactions and turbulence is not sufficiently understood to design flameless combustors, especially for gas turbine application. To numerically investigate mild combustion properties, Large Eddy Simulation (LES) is a good candidate. Indeed, high-fidelity simulations of non-premixed turbulent combustion regimes requires an accurate description of the fuel and oxidizer mixing that cannot be achieved under steady assumptions (RANS).
Thus, the aim of this study is to investigate the combustion process of natural gas in the distributed reaction regime (hence in flameless-like mode) using Large Eddy Simulations (LES) and complex chemistry. Lab-scale flames, with relatively simple geometries, will be considered, for which accurate experimental data are available. Effects of numerical discretization, chemical mechanism, operation type (premixed vs. non-premixed), and heat-losses at the walls will be studied and compared. The comparison with experimental data from the literature will give confidence in the quality of the predictions. Deeper knowledge of coupling between reactions and flow dynamics will be achieved through analysis of numerical results (modal analysis, etc.), bringing new insights into the flameless combustion process and providing recommendations for further experimental investigations.
Also in this case, particular attention will be devoted to the mechanisms leading to the formation of pollutant specie

Expected results. Better understanding of interactions between reactions and fluid dynamics in premixed and non-premixed flameless combustion.          

Planned secondment.  DE-TUD (8-10 months). Application of numerical techniques based on the tabulation of chemistry to LES of combustion devices with complex geometries.

Latest News

Good News

“Great news! Three of our ESR fellows have already been offered a Researcher position at top EU Universities!”


The CLEAN-Gas Project has received funding from the European Union’s Horizon 2020 Programme for research, technological development, and demonstration under grant agreement no. 643134-CLEAN-Gas.



Scientific Programme

One of the originalities is to link the different teams together with four additional industrial partners in order to suggest and develop new complementary perspectives combining mathematics and physics, chemistry and fluid mechanics, computation and experiments, all these different approaches aiming at a final real scale application for industrial use by companies.

Educational Programme

One innovative aspect of the program is to offer an extensive and prospective view of research to candidates with the goal to prepare them to become the researchers of tomorrow. The candidates' education will not be only a scientific research program, but also instruction on how to develop their understanding of research, their own responsibilities and their professional abilities.

Mobility Programme

Mobility is essential for research. Candidates will spend a first year mainly dedicated to their learning and knowledge development in one or the two co-tutelle institutions, followed by 1 or 2 semesters of intensive exchanges between the two. Then candidates will take a step back during the last semester for the synthesis of the work.
