| 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 accident statistics show that the smoke event probability is greater than 1/10000, so the smoke detection and airworthiness approval process should be considered. This article utilize the software of computational fluid dynamics (CFD) to research the influence of the different temperature of the smoke source on smoke diffusion. According to the simulation results, it exists a great gap between thermal buoyancy, gravity and the force of particles under different smoke source temperature, then seriously affects the smoke diffusion and the smoke detection time in aircraft cargo compartment. |
