Abstract

Abstract: The nonlinear hyperbolic conservation laws of the transient flow of the media in gas pipeline are hard to be solved，so，the control conservation laws are constituted of mass，momentum and energy conservation laws，TVD/Godunov hydrid algorithm is used to simulate the transient flow in gas pipeline，and the traditional splitting approach processing nonlinear convection in momentum equation is dismissed，the convection term is directly processed，in the way，the stablization of the algorithm and emulating accuracy of the transient flow are greatly improved.The time splitting approach is used in the algorithm to describe not completely blocked pipeline，the computing result of ideal accuracy is obtained.

Key words: natural gas pipeline, transient flow, nonlinear, TVD/Godunov hybrid algorithm, numerical simulation
