环境条件变化对热油管道停输降温过程的影响分析

Analysis of the Influence of Environment Changing on the Shutdown Course in the Hot Oil Pipeline

建立了热油管道停输降温过程的数学模型 ,使用数值方法 ,模拟了长距离埋地热油管道的停输降温过程 ,分析了环境条件变化 (季节、天气降温、管道沿线大范围突降暴雨 )对降温过程的影响。

The numerical model of shutdown of hot oil pipeline buried is proposed and the course of shutdown is simulated by using numerical method. The influence of environment changing on the course is analyzed.
