埋地天然气管道泄漏数值模拟
Numerical Simulation for the Leakage of Buried Natural Gas Pipeline
摘要
Abstract
The leakage geometry region of natural gas pipeline was provided. The leakage control equation of natural gas was established on the control volume principle and porous media theory. The numerical simulation was performed on the leakage of buried natural gas pipeline by using computational fluid dynamics software. Through the process of simulation, the concentration distribution of leakage natural gas in soil and air were got. The wind speed affect the diffusion law of natural gas was analyzed, the safe region was confirmed. The theoretical reference for emergency rescue and safety management of natural gas pipeline leakage was provided.关键词
