摘　　要：风是重要的战场环境因素,极易对烟尘、扬尘等气溶胶的分布状态造成影响。为得到侧向风对坦克行驶扬尘质量浓度分布的影响规律,基于离散相扩散模型,采用Fluent流体仿真软件对某坦克行驶过程中的扬尘释放与扩散过程进行仿真模拟,得到不同速度侧向风下的扬尘质量浓度分布数据。选择坦克车后3个典型区域进行分析,结果表明:每个区域质量浓度整体有随着风速增大而降低的趋势;坦克车尾附近区域受湍流影响严重,质量浓度值随风速变化存在明显波动;远离车尾区域扬尘质量浓度随风速的增大而下降明显。Wind is an important factor in the battlefield environment,which can easily affect the distribution of aerosol such as smoke and dust.In order to obtain the influence law of lateral wind on the dust concentration distribution,Fluent software was used to simulate the release and diffusion processes of dust during tank running based on the discrete phase diffusion model,and the mass concentration distribution data of moving dusts under lateral winds with different speeds were obtained.Three typical regions behind the tank are selected for analysis.The results show that the mass concentration of dust in each region decreases with the increase in wind speed.The region near the rear of tank is seriously affected by turbulence,and the mass concentration value fluctuates significantly with the change of wind speed.With the increase in wind speed,the mass concentration of dust in the region away from the rear of tank decreases significantly.This study provides a basis for improving the effectiveness of the laser fuze in the dust environment.
