Abstract

This paper presents the results of an experimental study of flames propagating with an alternating-sign velocity in methane–air and coal dust–methane–air mixtures in a vertically located closed tube at coal dust concentrations of 0.10–0.42 kg/m³. The results of the study can be useful for developing combustion models and assessing dynamic and thermal effects during combustion of methane–air–coal dust mixtures in coal mines.

密闭垂直管内甲烷-空气和甲烷-空气-煤尘混合物中速度变化的火焰

摘要本文研究了煤尘浓度为0.10 ~ 0.42 kg/m3时，火焰在垂直密闭管内甲烷-空气和煤尘-甲烷-空气混合物中以交变速度传播的实验结果。研究结果可为建立燃烧模型和评估煤矿甲烷-空气-煤尘混合物燃烧过程中的动力和热效应提供参考。

期刊介绍： Combustion, Explosion, and Shock Waves a peer reviewed journal published in collaboration with the Siberian Branch of the Russian Academy of Sciences. The journal presents top-level studies in the physics and chemistry of combustion and detonation processes, structural and chemical transformation of matter in shock and detonation waves, and related phenomena. Each issue contains valuable information on initiation of detonation in condensed and gaseous phases, environmental consequences of combustion and explosion, engine and power unit combustion, production of new materials by shock and detonation waves, explosion welding, explosive compaction of powders, dynamic responses of materials and constructions, and hypervelocity impact.
