Abstract

This paper first presents particle image velocimetry measurements of the chemical time scales versus equivalence ratio and the concentration of the inhibitor trimethyl phosphate for premixed methane–air and dimethyl ether–air flames at atmospheric pressure. Comparison of the experimental results with theoretical estimates based on the Zel’dovich–Barenblatt hypothesis shows their qualitative agreement. Within the accuracy of the experiment, the chemical time scale depends only on the burning rate, rapidly decreasing as it increases. At fuel–air flame speeds close to and above 0.6 m/s, the results of the experiments show the high accuracy of theoretical estimates based on the Zel’dovich–Barenblatt hypothesis.

用粒子图像测速仪估算层流火焰的特征时间尺度
摘要 本文首先介绍了粒子图像测速仪对常压下甲烷-空气和二甲醚-空气预混合火焰的化学时间尺度与等效比和抑制剂磷酸三甲酯浓度的测量结果。将实验结果与基于 Zel'dovich-Barenblatt 假设的理论估算结果进行比较后发现,两者在质量上是一致的。在实验精度范围内,化学时间尺度只取决于燃烧速率,并随着燃烧速率的增加而迅速减小。在燃料-空气火焰速度接近和超过 0.6 米/秒时,实验结果表明基于泽尔多维奇-巴伦布拉特假说的理论估算具有很高的准确性。

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.
