          Abstract

          The industrial Chair PERCEVAL is focused on advanced studies on the optimisation of combustion efficiency and reduction of pollutants of innovative injection systems by means of improved experimental understanding and modelling of the underlying generating mechanisms. Indeed deeper investigations of the physical processes encountered in combustors technologies such as the fuel injection systems are needed to provide background knowledge for the future design of aero-combustion engines. The emphasis will be on balanced efforts in basic and based-technology researches by the laboratory about the physical and chemistry mechanisms interacting together in lean combustion (spray injection, evaporation, fuel/air mixing, combustion efficiency, heat transfer, combustion instabilities, pollutants…), on the one hand, and transmission and know-how to the industrial partner, on the other hand. The originality of this chair is related to the combination of advanced time-resolved laser diagnostics and analysis techniques with high-resolution time-resolved Large-Eddy simulation in a focused and highly-integrated program of scientific and technical research. Experiments will be conducted in a new high-pressure high-temperature optical combustion facility fed with innovative lean fuel injection systems designed by the industrial partner. The Chair will be hosted by CORIA joint laboratory organized between CNRS, University of Rouen and the Engineering School INSA-Rouen and the industrial partner is the engine developer Safran group. CORIA contributes through its recognized expertise of numerical simulation, laser diagnostics measurements and experiments in large-scale combustors. The Chair holder Frédéric Grisch will be a full professor recruited two years ago to reinforce research on aeronautical combustion. Frédéric Grisch was a senior researcher in Onera before his transfer to CORIA with a project to strengthen the collaboration with Safran group in combustion systems. The scientific program is divided in five work packages addressing innovative laser diagnostics, experimental validation of lean injection systems, advanced LES numerical simulations, data processing tools and joint numerical-experimental joint analysis, and know-how transmission. The Chair will partly operate as a support of the C-CAAF (Centre de Combustion Avancée pour l’Aéronautique du Futur) research program. The final objective, apart from gathering fundamental and applied knowledge, is to increase the competiveness of the industrial partner and to power the future with clean and efficient aero-engines according to the ACARE FLIGHTPATH 2050 objectives.
