In this paper, computational fluid dynamics method was applied for the numerical simulation of a flat and open wind field. The dispersion of anti-infrared smoke screen in this area was evaluated by discrete phase model, and the three-dimensional distribution of the concentration of anti-infrared smoke screen was obtained. The efficient shielding region of anti-infrared smoke screen across the wind direction was calculated by using Lambert-Beer law. The relationship between wind velocity and shielding region of anti-infrared smoke screen was also studied in this paper.
