| 摘 要： | 采用了克兰克-尼科尔森(Crank-Nicolson)格式对天然气长输管道不稳定流动的数学模型进行了数值求解.考虑城市用气变化规律,对长输管道末端储气问题进行了研究,并通过实例对研究结果进行了分析.天然气在长输管道中的流动是不稳定流,因而不能按照天然气在低压、小流量、短距离输送工况下稳定流的方法进行分析、研究.

| Abstract: | This paper uses Crank-Nicolson mode to resolve the transient flow in long natural gas pipelines. Considering the gas consumption law of the city, gas storage in the end sections of long pipelines subject is studied. Finally, the paper uses a living example to analyze the result of study. Owing to the fact that natural gas in long pipeline is transient flow,the analysis method on stable stream can not be used to study the operating condition of pipeline under the low pressure,small volume of flow and short distance transmission mode. |
