燃气管道泄漏引发的温度变化研究

研究燃气管道泄漏引发的温度变化,可以构建燃气管道泄漏的光纤传感探测技术的理论基础。该文对燃气管道泄漏处产生的温度变化进行理论分析,对实际数据和物理模型进行了仿真分析。分析结果表明,基于泄露温度变化信号的光纤传感器检测技术具有两个优点:1)对处于不同环境下的燃气管道存在一定的普适性;2)由于内部压力大而更容易发生泄漏的地方,极易被监测到。该研究对于分布式光纤传感器在油气管道故障监测中的应用有一定的指导意义。

Investigation on the Temperature Shift from Fuel Pipeline Leakage

The investigation on the temperature shift owing to the leakage of fuel pipelines is the fundamental research in the leakage's monitoring technology based on optical fiber sensors. This paper presents a theoretical analysis of the temperature shift caused by fuel pipeline leakage. The simulation in combination of real data and physical model shows that the monitoring technology based on optical fiber sensors is universally applicable to fuel pipelines that lie in different surroundings, and the easier the fuel pipeline leakage occurs (owing to a larger pressure), the easier this leakage is monitored.
