A 2D planar representation of a generic laboratory-scale combustor is simulated to assess the capabilities of reduced models for representing realistic combustion flowfields. The generated simulation dataset is established and made public to provide a testbed to build reduced models for relevant challenging reacting flow problems using different methods.
