摘要
本文对燃气长输管线末段储气问题根据流体动力学规律建立长输管线的不稳定流动的数学模型，进行数值求解，可用于有变管径和有分输气的燃气长输管线的水力工况计算以及末段储气量的计算。实例计算结果表明按不稳定流动方法计算的末段储气量比按稳定方法计算的值高出１３．３９％。
This article presents a mathematical model of transmission pipeline unsteady flow for hydraulic calculation of the pipeline with branches and tubes of variety of diameters and end pipeline gas storage problem. Case study shows that for end pipeline gas storage capacity,calculation result of unsteady flow is great than that of steady flow.
