多火焰燃烧相互耦合作用研究

Study on the Coupling Effect of Multiple Combustion Flames

为研究多火焰共同燃烧时相互作用规律,从试验和理论分析两个方面对蜡烛燃烧耦合模式的影响因素进行研究。结果表明:当燃烧火焰相互靠近时会出现复杂振荡行为,该行为包括同相位同步振荡、反相位同步振荡和特殊的死亡模式;蜡烛间距、数量、对称性和拓扑结构是影响燃烧火焰之间相互耦合作用的主要因素;耦合模式由蜡烛间距决定,而蜡烛数量和拓扑结构对火焰振荡频率和亮度产生影响。

In order to study the interaction law of multiple flame combustion,the influencing factors of the coupling mode of candle combustion was investigated experimentally and theoretically.The results show that complex oscilla⁃tions occur when the flames are close to each other,including in-phase synchronization,anti-phase synchronization and special death modes;candle spacing,number,symmetry and topology are the main influencing factors between the burning flames.The candle spacing determines the coupling mode,and the topology and number of candles affect the flame oscillation frequency and luminous intensity.
