摘要: 受管道的自然寿命和人为因素等的影响, 管道泄漏事故频繁发生, 及时发现管道泄漏和确定泄漏点
位置对减少损失、 维护管道安全运行显得十分重要。针对成品油管道泄漏, 利用C F D仿真模拟软件模拟了管道压力
的变化。若管道始末端的压力发生改变, 则说明管道的某处已发生泄漏, 此时可根据管道始末端的压力梯度变化,
利用压力梯度法最终确定泄漏点的位置。

Abstract: Because of the natural life of the pipeline and the impact of artificial factors, pipeline leakage accidents occur frequently. It is very important to detect pipeline leaks and determine the leak location to minimize damage and maintain the safe operation of the pipeline. Be aimed at the products pipeline leak, the CFD simulation software was used to simulate changes in the pipeline pressure. Once the pressure changed at the pipe end and beginning, the pipeline leak happened somewhere. Then under the pressure gradient changes of the pipeline end and beginning, the pressure gradient method was used to ultimately determine the leak location of the pipeline. 
