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
The process and physical mechanism of water mist suppression diffusion flame were studied by experiments and numerical simulation. Water mist suppression diffusion flame is mainly through the vaporization of oxygen, cooling fuel and oxidants and absorbing part of the heat radiation to reduce heat feedback and other effects, reduce the chemical reaction rate and flame propagation rate, to control and extinguish the purpose. In ventilation control, the worse the ventilation condition, the better the suppression effect. Based on the experimental study, a one-dimensional numerical model of single-nozzle water mist suppression diffusion flame is proposed, which is simple and reasonable
