- 摘要:
- 为了研究燃油流量对防火试验火焰特征的影响，为防火试验方案的设计提供参考和指导，采用Ansys Fluent软件对NexGen燃烧器进行三维定常数值模拟，分析了不同燃油流量条件下的火焰特征。结果表明：燃油流量对火焰最高温度和火焰形状几乎没有影响，但对火焰长度、监测面上温度分布、7个测量点的平均温度和热流密度有很大影响，通过分析各燃油流量条件下的火焰特征，发现当空气流量为35.8 g/s时，燃油流量在2.0~2.11 g/s——即余气系数为1.15~1.22时，能够用于防火试验。
- Abstract:
- In order to study the influence of fuel flow rate on the flame characteristics in fire test, so as to provide the reference and guidance for the design of fire test scheme, the three-dimensional steady numerical simulation on the NexGen burner was carried out by using the Ansys Fluent software, and the flame characteristics under different conditions of fuel flow rate were analyzed. The results showed that the fuel flow rate had almost no effect on the maximum temperature and shape of flame, but had great effect on the flame length, the temperature distribution on the monitoring surface, and the average temperature and heat flux of seven measuring points. Through analyzing the flame characteristics under different fuel flow rates, it showed that the air flow rate of 35.8 g/s combining with the fuel flow rate of 2.0 to 2.11 g/s, namely the excess air coefficient of 1.15 to 1.22, can be used for the fire tests.
