Open publisher page 0 citations

Abstract

Based on the fundamental flow equations of high-pressure gas pipeline, the numerical solution for unsteady-state flow was studied with the Central difference scheme. Considered the energy equation and urban gas regular, the problem of low calculation precision caused by ignorance of the energy equation was solved. During the variation of gas consumption with time, the dynamic simulation program was generated. Finally, a numerical example of engineering application was presented .
