  Ignition is a critical process in combustion systems. In aeronautical
combustors, altitude relight capacities are required in case of accidental
extinction of the chamber. A simultaneous study of light-round ignition in an
annular multi-injector combustor has been performed on the experimental and
numerical sides. This effort allows a unique comparison to assess the
reliability of Large-Eddy Simulation (LES) in such a configuration. Results are
presented in fluid dynamics videos.
