An instrumentation and optical diagnostic platform gathering various laser/optical diagnostic techniques (PIV, LDV for the characterization of the aerodynamic field, PDPA, GRT for the characterization of the distribution of fuel droplets, CARS for measuring the thermal field and main species concentration, OH-PLIF and Schlieren for analyzing the flame structure, LII, NO-PLIF, CO-PLIF for measuring pollutants in the flame, etc.). In this context, the “Centre de Combustion Avancée pour l’Aéronautique du Futur” (C-CAAF) recently created at CORIA is aimed at providing: CORIA contributes through its recognized expertise in numerical simulation, optical diagnostic measurements and experiments in large-scale combustors to improving the understanding of multi-scale multi-physics physical mechanisms governing the lean combustion of future combustion chambers. These scientific activities are performed in the 'Complexe de Recherche Interprofessionnel en Aérothermochimie' (CORIA) research laboratory, a joint research institute organized between the CNRS, the University of Rouen and the INSA-Rouen Engineering School. The scientific activities presented in this article are within the field of the design of new concepts of combustion chambers and the exploration of their benefits to increase the combustion and environmental efficiencies of advanced air-breathing propulsion systems.
