单环管网内气体瞬态流动分析

Analysis of Transient Flow in a Single-Looped Gas Lino,

本文从流体力学基本方程出发建立了单环管网气体瞬态流动数学模型(此数学模型不仅适合于瞬态流动,同时也适用于稳态流动)。运用数理方法求出沿管线压力分布的解析表达式。适应输气量随时变动情况下的计算。编制了计算机程序,同时例举了算例。

This paper proposed a mathematical model based on the basic equations of fluid mechanics to simulate the transient flows for Single-Looped gas lines ( It is also applicable to the steady-state flows ).On mathematical equation for calculating pressure profile is obtained by a method of mathematical fhysic. Finally a computer program for computing pipeline throutput voriable with the passage of time is presented.
