CERFACS develops all models and tools to perform Large Eddy Simulations (LES) of reacting flows in combustion chambers. The AVBP code of CERFACS (www.cerfacs.fr/cfd/parallel.php) is the official tool of the SAFRAN group and is used widely in France and Europe for LES of reacting flows.
Description / Description
Thermo-acoustic instabilities are a recurrent problem limiting the range of operation of the aeronautical and power generation gas turbine engines. Prediction of their appearance at the design stage is very difficult or even impossible today. The numerical approach that is Large Eddy Simulations (LES) is in this context very promising and recent applications prove the power of this new numerical tool. For this PhD thesis, the developement of LES will be continued in collaboration with the SAFRAN group to assess its predictability for real gas turbine geometries (complete geometrie) operated at various conditions.
