A technical gas turbine combustor has been studied in detail with optical diagnostics for validation of large-eddy simulations (LES). chemiluminescence, OH laser-induced fluorescence (LIF) and particle image velocimetry (PIV) have been applied to stable and pulsating flames up to 8 bar. The combination of all results yielded good insight into the combustion process with this type of burner and forms a database that was used for the validation of complex numerical combustion simulations. LES, including radiation, convective cooling, and air cooling, were combined with a reduced chemical scheme that predicts emissions. Good agreement of the calculated flame position and shape with experimental data was found.
