| 摘 要： | 在一定条件下,层流预混气体燃烧过程中可清晰地观察到多棱火焰现象。本文从燃料浓度、温度对燃烧速度、气流速度的影响出发,推导出了火焰面变化随空气消耗系数的关系式,并得出了形成多棱火焰现象的条件为:Kx<0。用该式判断的丁烷层流预混气体燃烧的多棱火焰区与实验结果基本吻合。

| Abstract: | The polyhedral flame has been observed clearly when butane burns in some laminar, conditions. By analyzing the effect of the air excess factor, the temperature on flame speed and flow velocity, the simple equation has been developed for the prediction of polyhedral flame: Kx < 0. Good agreement was obtained with the measurements for butane premixed laminar combustion. |
