摘要
输气管道的发展方向是大管径、高压力、长距离和调峰要求高,迫切需要对输气管道不稳定流动进行研究。基于流体力学基本原理推导的连续性方程、动量方程、能量方程以及SHB-WR真实气体状态方程,建立了燃气长输管道不稳定流动数学模型,采用隐式中心有限差分法编制了该模型的通用数值计算程序,结合哈—依燃气管道工程,将计算结果进行了整理、分析和验证,并在此基础上,对燃气长输管道末段储气量进行了研究。
With the construction of long-distance gas pipeline toward large diameter,high pressure,and high pack shaving requirement, the study of unsteady-state flow is in urgent need. In this paper according to the basic laws of hydrodynamics,the mathematics model,including equations of mass conservation,momentum conservation, energy conservation and SHBWR equation of state for real gases,is established. Based on the implicit central difference scheme,the general numerical simulation program of the model is developed. The program is validated in the Harbin-Yilan gas pipeline. Finally, final section line-packing of long-distance gas pipeline is studied.
