Swirl-stabilized, turbulent, non-premixed kerosene-air flames were investigated experimentally in a RQL (rich burn/quick-quench/lean-burn) model combustor with large optical accesses at elevated pressure. The goals of the investigations were a detailed characterization of the flame topology as well as the soot and NO formation processes produced in the rich primary zone of the RQL combustor and the establishment of a large data base for the validation of numerical combustion simulations
