摘要:
从软件仿真和实验室模拟试验两种方法,对城市燃气管道发生泄漏前后管道内流体的流动状态进行了分析对比,得出结论为管道是否发生泄漏提供了理论依据。运用计算流体力学Fluent14.0软件,分别模拟管道1、2和3 mm泄漏孔径状态下的流速以及压力参数的变化,分析得到管道泄漏前后,管道内流体流动参数的不同分布规律。然后通过实验室管道模拟泄漏试验,分别得到以上不同泄漏孔径下的管道压力、流量的变化趋势。将数值模拟结果与泄漏模拟实验结果相比较,所获得的压力和流速沿管道的分布、变化情况基本一致,为预判城市燃气管道泄漏与否提供了参考依据。
Abstract:
Based on the methods of software stimulation and laboratory simulation, the flow state of fluid in the city gas pipeline before and after the leak were compared and analyzed, which provides a theoretical basis for gas leak. By using Fluent 14.0, a numerical simulation software and simulating the flow rate for pipelines with 1, 2 or 3mm apertures and their changes of pressure in the pipelines, the distribution of fluid parameters was obtained. Through simulating experiment for pipeline leak, the trend of pipeline pressure and flow rate was obtained, respectively. A comparison of the numerical simulation result and simulated experimental result indicated that, the pressure and flow rate are basically the same, which provides a reference for the prediction of city gas pipeline leak.
