针对民用飞机灭火系统的特点,使用商业软件FLUENT对民用飞机发动机舱着火后灭火剂的雾化过程进行数值仿真模拟,分析发动机舱着火状态下灭火剂喷射后舱内灭火剂浓度的分布情况,为民用飞机发动机灭火系统设计提供技术支持。
In view of the characteristics of the civil aircraft fire extinguishing system, the commercial software FLUENT was used to simulate the atomization process of the fire extinguishing agent after the fire in the engine compartment of the civil aircraft. The distribution of fire extinguishing agent concentration in the cabin after the fire extinguishing agent was fired in the engine compartment was analyzed. Civil aircraft engine fire extinguishing system design to provide technical support.
