Numerical Simulation of Natural Gas Pipeline Leakage

Natural gas pipelines are very important to the national economy. Unfortunately, leakage of natural gas pipelines often occur with many reasons such as corrosion, third-party interference and so on, which can lead to damage to property and life. Thus, the size of the diffusion region of the leakage is very important to repair quickly, which can prove dangerous area after a leak. This paper uses the software FLUENT to simulate the diffusion rule of natural gas pipeline leakage after ruptured and analyzes the influence of different wind velocity, leakage rate and the spread of the terrain. The analysis shows that all factors will increase the danger of gas leaks after diffusion, in which the leakage rate and wind velocity are much larger.
