自然通风条件下催泪剂室内扩散特性的模拟研究

Simulation Study on Interior Lachrymator Diffusion under the Condition of Natural Ventilation

为评估催泪弹室内的作用效能,依据粒子的动力学模型,采用Fluent软件对催泪剂的室内扩散特性进行了模拟研究。结果表明,在自然通风的条件下,无论是竖直方向还是水平方向上,越靠近窗口催泪剂的浓度会越低,但总体而言,由于不受外界的影响,催泪剂不易扩散,浓度基本维持在0.7~0.9的范围内。

In order to evaluation the efficiency of the tear bomb indoor, according to the dynamic model of the particle, the indoor lachrymator diffusion under the condition of natural ventilation was simulated by the Fluent. The results show that the nearer to the window, the lower the relative concentration of lachrymator, whether it is vertical or horizontal direction. While without the influence from outside world, the lachrymator is not easily diffused, the concentration of the lachrymator is adjusted to maintain the range 0.7 to 0.9.
