PhD defense – Felix COLLIN BASTIANI : “Modeling and Large-Eddy Simulations of Two-Phase Ignition in Gas Turbines”

Marie LABADENS |  CERFACS, Toulouse (France) conference room J.-C. André |  

Abstract

In order to meet the new international environmental regulations while maintaining a strong economic competitiveness, innovative technologies of aeronautical combustion chambers are developed. These technologies must guarantee fast relight in case of extinction, which is one of the most critical and complex aspects of engine design. Control of this phase involves a thorough understanding of the physical phenomena involved.
In this thesis the full two-phase ignition sequence of an aeronautical engine has been studied, from the breakdown of the spark plug to the propagation of the flame in the complete engine. For this purpose, Large-Eddy Simulations (LES) using a detailed description of the liquid phase (Euler-Lagrange formalism) and of the combustion process (Analytically Reduced Chemistry) were performed. The results also led to the development of a simplified model for the prediction of ignition probability map, which is particularly useful for the design of combustion chambers.
