| 摘 要： | 基于相似理论,在试验室建立系统模型,利用示踪技术进行模型试验,在获取试验数据的基础上,对有害气体泄漏扩散过程作了定性和定量分析。定性分析结果表明,该扩散过程存在两个相似准则π1=cx3/Q和π2=v·x/t,对应的准则方程为c=Q/x3·f(v·x/t);以定量分析法对有害气体泄漏扩散方程进行了推导,得出其数学表达式为c=23.1·Q·(t0.4/v0.6·x2.4)。认为研究结果对泄漏事故扩散趋势可以做出准确的预测,有助于建立有针对性的应急救援预案,实施有效的现场控制。

| Abstract: | A system model is constructed in laboratory based on similarity theory and a model experiment is carried out using tracer technique. Having obtained experimental data,qualitative and quantitative analysis are performed to the diffusion rule of the harmful gas. The results of qualitative analysis showed that there exist two similarity criterions: and,their corresponding criterion is;the diffusion equations are deduced by quantitative analysis,and the mathematical representation is obtained:The research has a certain reference value to trend prediction,establishment of emergency response rescue plan and implementation of effective field control. |
