摘要
为得到燃气泄漏扩散规律,更好地减少燃气事故所造成的人员伤亡和损失,据相似理论,建立系统模型并进行模型试验,在获取不同空间点燃气的浓度和采集燃气管道的泄漏速率的基础上,对温度、湿度等多因素耦合作用下的燃气泄漏扩散作了多元回归分析。运用相似准则和量纲分析理论结合多次反复的试验,定量研究确定多因素作用下的燃气泄漏扩散方程并进行验证,为燃气泄漏扩散预测和应急救援提供可靠的理论依据。
In order to reduce the casualties and damage caused by gas leakage,and to get the diffusion law of gas leakage,a system model is constructed and tested based on similarity theory.Multiple regression analysis of the diffusion law of gas leak with temperature,humidity and other factors coupled based on the concentration of different spatial points and the gas leakage rate of gas pipeline have been done.The gas leakage diffusion equation has been established and been verified through the test repeatedly on similarity theory and dimensional analysis.This result of research has a reliable theoretical basis to probable gas leakage prediction and emergency relief measures.
