Modélisation de la combustion turbulente via une méthode de tabulation de la cinétique chimique détaillée couplée à des fonctions de densités de probabilité. Application aux foyers aéronautiques

Abstract : A new modelisation of turbulent combustion is proposed with detailed chemistry and PDFs. The objective is to capture temperature and species concentrations, mainly the CO. The PCM-FTC model, Presumed Conditional Moment – Flame Tabulated Chemistry, is based on the tabulation of laminar premixed and diffusion flames to capture partial premixing present in aeronautical engines. The presumed PDFs is introduced to predict averaged values. The tabulation method is based on the analysis of the chemical structure of laminar premixed and diffusion flames. Hypothesis are presented, tested and validated with Sandia experimental data jet flames. Then, the model is introduced in a turbulent flow simulation software. Three configurations are retained to quantify the level of prediction of this formulation : the D and F-Flames of Sandia and lifted jet flames of methane/air of Stanford. A good agreement is observed between experiments and simulations. The validity of this method is then demonstrated.
