Aeroengines

Cagire is presently involved in studies mainly related with two subcomponents of the combustion chamber of aeroengines:

• The combustion chamber wall: the modelling, the simulation and the experimentation of the flow around a multiperforated plate representative of a real combustion chamber wall are the three axes we have been developing during the recent period. The continuous improvement of our in-house test facility Maveric is also an important ingredient to produce our own experimental validation data for isothermal flows. For non-isothermal flows, our participation in the EU funded program Soprano will be giving us access to non-isothermal data produced by Onera.

• The fuel nozzle: the impact of small geometrical variations related to the fabrication process on the pressure losses of the injector is being studied for a generic geometry provided by our industrial partner AD Industrie. RANS based simulations are intended to help designing some critical components of the fuel nozzle. A project is currently written to answer a call of the Nouvelle Aquitaine region, with the objective of extending this study to hybrid RANS/LES methods.
