摘要
该文通过对大气输运与扩散过程的分析 ,探讨了诊断风场模式在计算烟幕施放区域风场中的应用 ,分析了烟源在大气作用下的弥散特性 ,提出了烟幕弥散的仿真模型。通过该模式与高斯模式的对比分析表明 ,该模型具有原理准确、结构简单、可操作性强等优点。该模型可以作为烟幕浓度的估算依据。
Based on analyzing atmosphere transportation and diffusion process,this paper studies the application of a diagnosis mode to calculating the wind field of the release district, analyzes the dispersion characteristics of smoke source in the atmosphere, and brings up an imitation model of the dispersion of screening smoke. Compared with the gauss model,the research shows that this model possesses such advantages as high determinability and operability. The model can be applied to estimating the concentration of screening smoke and the attenuation of light intensity.
