Abstract
Influence of wall is one of the important subject in combustors because many combustors, such as internal combustion engines, are surrounded by walls. Especially, the influence becomes more important in ultra-micro combustors. We aim to reveal the mechanisms of surface reaction on flame-wall interaction. In this study, we focus on OH radicals, which play important role in surface reaction, in stagnation flames. The temperature and the materials of the stagnation plate are changed, and the distributions of OH radicals are measured by OH-PLIF. The results suggest the influence of surface reactions in each material.
