报告了预混合平焰的绝热燃烧速度和乙烷+氧气+二氧化碳的绝热蜂窝火焰混合物的传播速度。人造空气中的氧含量O 2/( 2 + CO2)在26％至35％之间变化。非拉伸火焰在多孔板燃烧器上稳定在1atm通量下，用于确定净热损失为零时条件下的燃烧速度。在特定的实验条件下，火焰会变成细胞状；这导致火焰传播速度显着改变。介绍了细胞火焰的测量结果，并将其与扁平火焰的测量结果进行比较，并与理论模型的定性预测进行比较。在所研究的混合物的整个化学计量范围内均出现细胞结构。当火焰变得稍微亚绝热时，细胞结构消失。 2003 年燃烧研究所。由爱思唯尔公司出版。保留所有权利。埃森斯·奈特，一个罗特·塔·阿格·埃雷·塞斯（Ers ons Nethe），将自己的余生时代的麻醉作为安宁的一部分。
Adiabatic burning velocities of premixed flat flames and propagation speeds of adiabatic cellular fla mixtures of ethane+ oxygen+ carbon dioxide are reported. The oxygen content O 2/( 2 + CO2) in the artificial air was varied from 26 to 35%. Nonstretched flames were stabilized on a perforated plate burner at 1 atm flux method was used to determine burning velocities under conditions when the net heat loss of the zero. Under specific experimental conditions the flames become cellular; this leads to significant modific the flame propagation speed. Measurements in cellular flames are presented and compared with those f flat flames and also with qualitative predictions of a theoretical model. The onset of cellularity was ob throughout the stoichiometric range of the mixtures studied. Cellularity disappears when the flames beco slightly subadiabatic. 2003 The Combustion Institute.
