抄録
内容記述 In this study, we numerically investigated downward flame spread over a thin solid fuel in partially premixed atmospheres. For simplicity, we assumed that the pyrolysis gas consists of methane and nitrogen. To consider the partially premixed atmospheres, methane was added in the opposed air stream. The fuel concentration was kept below the lean flammability limit. For discussing the flame structure, the flame index was obtained to observe premixed and non-premixed flames. Results show that, in the partially premixed atmospheres, the flame spread rate is increased. The high temperature region is enlarged. The premixed flame region is expanded at the leading flame edge, with larger flame temperature. This is because the heat transfer to the unburned solid fuel is intensified. As a result, amount of ejected fuel velocity from the solid surface is increased, which supports the higher flame spread rate in the partially premixed atmospheres.
