Wall cooling in aero engine gas turbine combustors is one of the main issues in the development of advanced combustion concepts, especially for lean combustion technology. Here fuel is burned in a mixture with a lean equivalence ratio and the CO oxidation is prone to quenching effects caused by mixing processes between cooling film and reacting burner flow. The information about the distribution of CO concentrations is of great interest in such a configuration in order to increase the understanding of the impact of large scale mixing processes. Up to now planar laser measurements of the CO emissions within the flame region have not been realized under realistic operation conditions such as elevated pressure. A new planar and quantitative CO LIF measurement technique has been developed for measurements especially at elevated pressures and first results are presented in this contribution. Numerical simulations have been performed to support the measurements.
