Quantitative Measurement of Wall Chemical Effects for Hydrocarbon/Ammonia Flames

Japan Section

Full Description



Flame-wall interaction (FWI) plays an important role in the near-wall flame behavior of internal combustion engines, gas turbines, and other combustion systems. In microscale combustors, the FWI becomes significant due to the large surface to volume ratio, resulting in flammability and flame stability problems. Flame quenching due to heat loss to the wall has been intensively studied, but it was only recently that strong wall chemical effect was observed through OH planar laser induced fluorescence (OH-PLIF) measurements of a methane/air premixed flame in micro channels. We found that the near-wall OH concentration is significantly affected by the surface materials at high wall temperatures (≥800 ºC). It was also revealed through high-spatial-resolution two-photon absorption LIF (TALIF) of H/O atoms in the hydrogen flame that the initial sticking coefficients vary among radicals, and the H adsorption plays an important role for the radical quenching. The wall chemical effects are also investigated for a wall-stabilized cool flame. The ignition temperature changes significantly for different wall surface materials. Recently, we also investigate the FWI for ammonia flames; in ammonia flames, the flame structures are affected by the wall chemical effects, while the composition of wall surface materials is also affected by the ammonia flames through nitriding. In this talk, two-way coupling between ammonia flames and wall surface materials will be discussed in detail.
