天然气泄漏扩散模型研究

Study on Natural Gas Leak Diffusion Model

在天然气集输过程中,由于管道系统连接件之间的密封缺陷、腐蚀穿孔、人为管理不善等因素引起的天然气泄漏甚至爆炸事故在国内外屡见不鲜,对于长输天然气管道泄漏过程研究应用,可有效减少因天然气扩撒、爆炸等引起的人员和经济损失,而研究的关键则在于模型的建立。

In natural gas gathering and transportation process, natural gas leak and explosion accidents caused by sealing defects of the connection between the pipe system, corrosion perforation, human mismanagement and other factors are common at home and abroad. Studies on long-distance gas pipeline leakage process can effectively reduce human and economic losses caused by natural gas leak diffusion, explosion and other reasons. The key of the studies lies in the establishment of the research model.
