| 摘 要： | 利用普朗特边界层微分方程,根据爆炸成烟烟幕云团的自身运动特点,通过在不同条件下的假设,建立了贴地面的烟幕云团的边界层流动数学模型,以及快速成烟膨胀模型,并用实验分析模型。研究认为,在爆炸成烟烟幕云团形成初期,其流动特征为湍流,空气阻力是烟幕云团膨胀运动速度迅速衰减的主要原因。

| Abstract: | The obscuring performance of smoke cloud was influenced by different turbulent diffusion characters.The initial flow ability of exploding smoke cloud was studied in this paper.Based on the differential equations of the Plandtl boundary layer and performance of smoke cloud on the ground,flow model of the boundary layer and formation model of smoke cloud by blasting were established.According to experiments and the model hypothesis under different conditions,the initial flow ability of smoke cloud forming was analyzed.The results show that the flow of the smoke cloud is mainly turbulent,and its expanding velocity is attenuated rapidly by air drag. |
