Advanced Simulation of Aeronautical Combustors

The development of new aeronautical combustor concepts relies on the best possible knowledge of combustion phenomena, such as ignition and extinction, flame structure, combustion instabilities or pollutant emissions. Numerical simulation, and in particular the Large Eddy Simulation approach, is a powerful tool to understand, predict and control the coupled physics involved in turbulent combustion in both academic and applied configurations. Thanks to reliable physical models, accurate numerical methods and high efficiency on massively parallel computers, numerical simulation is now able to produce robust and reliable solutions in complex geometries, taking into account all technological and physical effects. Today, it is a research tool that contributes to improving our knowledge of turbulent reacting flows and in particular the interaction between turbulence and combustion chemistry. It is also an efficient tool for the design of aeronautical combustors, guiding test benches and possibly reducing their number.
