| 摘 要： | 通过实验和数值模拟研究了细水雾抑制扩散火焰的过程和物理机制．细水雾抑制扩散火焰主要是通过汽化隔氧、冷却燃料和氧化剂以及吸收部分热辐射降低热回馈等效应，降低化学反应速率及火焰的传播速率，达到控制和扑灭目的．在通风控制时，通风条件越差，抑制效果越好．在实验研究基础上提出单喷头细水雾抑制扩散火焰的一维数值模型，简单合理 |
| 关 键 词： | 细水雾，扩散火焰，抑制，汽化隔氧，冷却，吸收热辐射 |

| Abstract: | The mechanism and process to suppress diffusion flames with water mists have been experimentally studied and numerically simulated. The water mist suppresses diffusion flames through oxygen displacement, evaporation cooling and heat radiation attenuation, which slow down the reaction and fire spread. The poorer the ventilation, the easier the suppression. The one dimensional model based on experiments is simple and reasonable. |
| Keywords: | water mist suppression diffusion flame oxygen displacement evaporation cooling heat radiation attenuation |
