【摘要】 随着天然气管道工程发展,并行铺设管道的安全问题逐渐成为天然气管道安全系统的重要研究。通过数值模拟不同环境风速管道天然气泄漏燃烧过程,得到不同环境风速下喷射火的速度、温度以及热辐射的分布规律,进而分析失效天然气管道喷射火对相邻天然气管道的影响。研究结果为基于规避风险的优化天然气管道系统设计、实际安全生产和应急救援提供了理论基础。更多还原

【Abstract】 With the development of natural gas pipelines, the safety of paralleled pipelines has become an important research of natural gas pipeline safety system. Through the analysis of simulating cases on natural gas pipeline leakage and jet fire process in conditions of different wind speed, the velocity,temperature and heat radiation distribution law of jet fire are obtained to analyze the influence on adjacent natural gas pipeline. The results could be applied to optimize the design of natural gas pipeline system based on risk aversion, and provide theoretical basements for practical safety production and emergency rescue.更多还原
