| 摘 要： | 在气体协流管式燃烧器研究的基础上,利用高速纹影系统对细水雾作用下层流预混火焰拉伸、熄火规律进行了实验研究,并分析了细水雾抑制气体预混火焰的条件.实验结果表明：火焰面拉伸规律与燃料浓度、气体流量以及水雾雾滴直径有关;对于大滴径协流水雾,水雾载荷比越小,火焰面拉伸现象越明显.

| Abstract: | Based on the tubular burner, the laminar premixed flame stretch mist were studied by employing the high speed schlieren system. and inhibition by co-flow water The conditions and inhibition phenomenon were also analyzed. It is shown that the flame stretch is related to fuel concentration, co-flow fluxes and water mist diameters, and for the larger diameter droplets the smaller the co-flow fluxes, the more obvious the flame stretch. |
