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 |  


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.

Sparse Days Meeting 2019 at Cerfacs, Toulouse

Brigitte Yzel |  12 May 2019

The annual Sparse Days meeting will be held at CERFACS in Toulouse on 11th and 12th July 2019. Registration for the Sparse Days is free but we ask people who are coming to register as soon as possible although the deadline is June 14th. Please complete the registration form (deadline : June 14th) indicating whether you want to give a talk and whether you wish to attend the conference dinner. Although an emphasis will be on parallel aspects, any talk that has an association with sparsity is welcome.Read more
