The interaction of flames and combustion chamber walls occurs in almost all common technical combustion systems. Incomplete combustion leads to an increased formation of pollutants in the area close to the wall. Current developments to increase the efficiency of internal combustion engines and aircraft engines are often based on reducing combustion chambers while maintaining or increasing performance. The more compact combustion chambers increase the surface-to-volume ratio, so that the flame-wall interaction will become more important in future combustion system developments. Because of the small space and time scales involved at which the flame-wall interaction occurs, the processes are largely unexplored and based on empirical relationships. Reliable validation data are required for the calculation using numerical simulation (CFD). In this work, therefore, laser-based methods are used to investigate the flame-wall interaction, which enable a quantitative determination of the flame extinction. For this purpose, methods for the simultaneous determination of the gas phase temperature and CO concentration as well as the investigation of the flame propagation were carried out and developed. The focus is on influencing the thermochemical state during transient flame extinction in contrast to stagnation-stabilized flames.
