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.
