Abstract :
Based on the theoretical analysis on the leakage process of natural gas pipeline, regarding pipeline and leakage point as a united hydrodynamic system, taking the influence between leakage point and flow in pipeline into account, and applies continuous equation, momentum equations and gas state equation, this paper establishes a leakage transient mathematical model before and after gas supply cutting off, solves the two types of models to simulate the change of leakage rate over time and the leakage duration after gas supply cutting off adopting orthogonal transformation method and Runge-Kutta method.
