Simultaneous Measurements of Flame Front Location and Wall Temperature during Flame-Wall Interaction
Résumé
Wall temperature and flame front location in the near-wall region of a V-shape turbulent methane/air flame are si- multaneously measured with ratiometric phosphor thermometry (PT) and planar laser induced fluorescence on the hydroxyl radical (OH-PLIF). After a presentation of the near-wall combustion test bench and the optical diagnostics, preliminary results of the impact of the bulk wall temperature on the flame topology are presented, where a slight flame thickening can be noticed when the bulk wall temperature increases.
