中文摘要：
采用Boussinesq近似模型与不可压缩模型研究了不同密度比的烟团在标准分层大气条件下的烟云运动过程,分析了两种模型计算烟云之差异,得出烟团密度与周围大气密度比越小,两种模型计算结果相差越大的结论,当密度比达到0.9时,两种模型计算结果基本一致,为研究爆炸烟云的运动提供参考。
英文摘要：
It is to study the rising of the explosion clouds in the normal atmosphere using Boussinesq model and the Incompressible model,the numerical model is based on the assumption that effects the clouds are gravity and buoyancy.By comparing the evolvement of different density cloud,and gives the conclusion-the Boussinesq model and the Incompressible model is accord when the cloud＇s density is larger compared to the density of the entironment.
