| 摘 要： | 火焰稳定器吹熄特性的研究过去均采用实验方法并归纳出经验公式。本文通过计算燃烧流场的稳态临界点来逐步逼近非稳态吹熄极限,提出了一种数值方法来近似预测钝体火焰稳定器的吹熄特性。

| Abstract: | Usually the stability of flame in the flameholder is determined by experiments or by semiexperimental expressions.An approximate numerical method to determine the blow-off limit is given in this paper.When a reacting flow is in a state of combustion,the computational results of the flow field behind a bluff-body will show a flame sheet expressed in terms of the temperatnre distribution.The blow-off limit can be approximately determined by calculating two critical states at which there is a flame sheet or not one respectively in the flow field. |
