摘要: 针对地铁站内脏弹爆炸烟团扩散问题,以计算流体力学(CFD)为理论基础,用FLUENT软件建立离散相模型(DPM)进行数值仿真。通过比较不同的爆炸载荷系数β和通风系统,分析了不同装药的脏弹对爆炸产生的PM10粒子在室内运动的规律和浓度,同时进一步研究了通风系统对颗粒扩散的影响,为脏弹恐怖事件的辐射防护和应急救援提供源项参考。

关键词: 脏弹, 烟团扩散, DPM, 颗粒物

Abstract: Based on the CFD theory, a discrete phase model (DPM) was developed using FLUENT for digital simulation. By comparing different explosive load factor β and ventilation system, the motion law and concentration of PM10 particles were analyzed. Finally, this paper studied the effect of ventilation system on particle dispersion and provided a theoretical reference to the radiological protection and emergency response to dirty bomb incidence.

Key words: dirty bombs, cloud diffusion, DPM, particulate matter
