Innovative low-carbon aero-engines rely on ultra-compact and high energy density combustors, increasing the thermal loads of the walls. This study aims at experimentally enhancing the understanding of the interrelated physical processes between a flame, a wall and a cooling technology. The test rig operates at atmospheric pressure and generates a methane/air turbulent flame interacting with a wall that is air-cooled by means of a splash cooling plate device. Optical diagnostics are simultane- ously implemented, including reactive particle image velocimetry (PIV) to assess the flow field, planar laser induced fluorescence on the OH radical (OH-PLIF) to study the flame structure, and laser induced phosphorescence to measure the wall temperature in contact with the reactive flow. Results show that the mean flame location is shifted away from the wall as the blowing ratio is increased. The wall temperature reveals that to enhance cooling efficiency, blowing ratio and flame location must not be considered without each other. Eventually, a classical flame-wall interaction process is retrieved when the blowing ratio is small, whereas flame strain, originating from the aerodynamic shear layer, pilots the flame dynamics for large blowing ratios.
