近年来，气溶胶作为一种无源干扰手段，以其较好经济性和较高的实用性得到了各国军方的重视并在现代高科技下的局部战争中得到广泛应用。基于牛顿第二定律建立了气溶胶粒子的运动方程，采用有限差分方法对粒子运动方程和气溶胶平流扩散方程进行差分运算，构建了重力作用下的气溶胶“沉降-扩散”联合动态模型，基于模型提出了气溶胶“沉降-扩散”联合动态数值模拟方法。以某自主开发的气溶胶材料为实验样品，模拟烟幕箱中气溶胶的“沉降-扩散”联合动态运动，研究气溶胶浓度的时域分布，并与烟幕箱采样实验结果进行比较。实验结果表明：气溶胶“沉降-扩散”联合动态模型能够较好地模拟气溶胶的动态特征，对研究气溶胶材料和发烟器性能、开展气溶胶干扰动态仿真实验、评估气溶胶干扰效能等具有重要意义。

In recent, aerosol which is a passive jamming method has been taken seriously by the military and has been widely used in the modern super-science local war because of its obvious economic benefits and great practicability. The aerosol particles′ motion equation was presented in this paper. By using the finite -difference method, the motion equation and a mathematical model of aerosol sedimentation and diffusion were given in difference expressions, and a dynamic model of aerosol sedimentation and diffusion was formulated. Method of numerical simulation of aerosol dynamic sedimentation and diffusion was presented. The consistence of the simulation experiment′s result and smoke chamber experiments show that the model presented in this paper can accurately simulate the motion of aerosol, which is significant in the research of aerosol material and aerosol behavior, the dynamic simulation experiment of aerosol jamming and the performance evaluation of aerosol jamming.
