摘要
建立了大加速度场中的层流预混火焰的一维模型，并应用改进的克莱法就加速度场对层流预混火焰传播速度及火焰面结构的影响以丙烷和空气的预混气为例进行了理论计算。通过分析计算结果，讨论了加速度对火焰传播速度、火焰面温度和密度分布及化学反应速率的影响及产生原因，为大加速度场中的燃烧试验提供了一定的理论指导。
Sets up the one-dimensionai model of premixed flames of laminar flow in large acceleration fi-eld. Numerical calculations for propane-air premixed mixture are carried out in order to find out the effects ofthe large acceleration field on the behaviors of premixed flames of laminar flow, by improved Klein method.The effects of large acceleration field on the beliaviore of flames are discussed, such as, flame propagationspeed, temperature and density distribution in the flame front, chemical reaction rate , and so on. A theoreticalguide is achieved for combustion experiments in large acceleration field.
