小空间重气扩散规律试验模型构建

Modeling the Spreading Pattern of Heavy Gases

基于相似理论对高速公路现场进行等比缩小,构建了小尺度空间重气扩散规律试验模型,并利用相似理论推导出重气扩散的准则方程。依据小尺度重气扩散试验模型在预设的参数条件下,可对重气扩散规律进行定性分析和定量计算,以指导消防部队对化学危险品泄漏事故的处置。

This paper models the experimental model of the spreading pattern of heavy gases in miniature based on the model in miniature obtained on a highway. The spreading pattern can be analyzed quantitatively and qualitatively based on the experimental mode with prescribed parameters.
