In recent years, hydrogen combustion in gas turbine applications has been identified as a key technology in the fight against climate change. However, the physical processes involved in the combustion of this fuel are not yet fully understood. Especially the interaction of hydrogen flames with enclosing effusion cooled walls is still subject to extensive research.

Using an atmospheric flame-wall interaction (FWI) burner and state of the art effusion cooled walls, a deeper understanding of the fundamental processes can be obtained. Using thermographic phosphors and embedded sensors, wall temperatures can be extracted. Information on gas temperatures, other flame properties like reaction zones as well as the flow field is extracted using OH-planar laser-induced fluorescence (OH-PLIF), coherent anti-Stokes Raman spectroscopy (CARS), 1D-Raman and particle image velocimetry (PIV). This data also provides the necessary basis for the development of numerical models in this field.
