侧向风下坦克行驶扬尘质量浓度分布规律仿真

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.
