The aviation industry is facing serious challenges to tackle the transition energy. New engine concepts are therefore considered, with increased energy density inside the combustor. Wall cooling is thus a critical concern, and flame-cooling air film-wall interaction (FCAI) become a critical process to better understand. In this study, the near-wall combustion test bench CENTOR is used to generate simplified FCAI events with a slot cooling device. Velocity fields, flame dynamics and surface wall temperature are simultaneously measured by particle image velocimetry (PIV), planar laser induced fluorescence on the hydroxyl radical (OH-PLIF), and phosphor thermometry (PT) for various blowing ratios. Mean fields and cooling effectiveness are analysed regarding the presence of the air film. A joint statistical analysis of the flame curvature and flame strain rate bring out the influence of the shear layer between both flows on the flame.
