天然气管道泄漏研究现状分析

天然气管道发生泄漏将造成重大经济损失和环境污染,严重危害泄漏点附近的人民的生命财产安全。因此,在天然气管道发生泄漏后及时准确的检测出泄漏点,以及研究天然气在不同介质中的扩散模型具有重大意义。概述了近年来在天然气管道泄漏方面的多项研究现状;其中最主要的方面在于利用CFD软件结合扩散模型对管道泄漏进行仿真研究。

Analysis on Current Research of Natural Gas Pipeline Leakage

The leakage of natural gas will not only cause great economic loss and environmental pollution, but also endanger the transportation security and life and property safety of the residents near the leakage site.It is very important to locate the leakage site immediately after the accident occurs and study the diffusion model of natural gas in different medium. In this paper, research status about natural gas pipeline leakage was summarized. One of the most important parts is using CFD software combined with diffusion model to numerically simulate the natural gas leakage.
