【摘要】：目前的事故统计数据表明飞机烟雾事件发生概率大于1/10 000,因此有必要关注烟雾探测系统的符合性及其适航审定过程。基于CFD软件,研究不同烟源温度对烟雾扩散规律的影响。由仿真结果得出不同烟源温度造成热羽流浮力与颗粒之间的作用力有很大差距,影响了飞机货舱内的烟雾扩散与烟雾探测时间。
[Abstract]:The current accident statistics show that the probability of aircraft smog event is more than 1 / 10, 000, so it is necessary to pay attention to the conformance of the smoke detection system and the airworthiness process. Based on CFD software, the effect of different smoke source temperature on smoke diffusion was studied. The simulation results show that there is a big difference between the buoyancy of heat plume and the interaction force between particles due to the different temperature of smoke source, which affects the smoke diffusion and smoke detection time in the cargo cabin of aircraft.
