| 摘 要： | 在考虑气候条件和启输温度变化的情况下,用有限单元法对管道周围土壤温度场进行了三维数值计算,得到了不同时刻的土壤温度场分布情况。同时,对不同温度热水预热时的埋地热油管道启输过程的土壤温度场进行了对比,结果表明,虽然提高预热介质的温度可以达到更好的预热效果,但过多提高预热介质的温度,并不能得到最佳的预热效果。

| Abstract: | Through the use of finite element method,three-dimensional numerical simulation about soil temperature field of buried pipelines was finished.In the course of calculation,climatic conditions and the temperature of the soil were considered.Then the soil temperature field around underground hot oil pipelines during the course of starting transportation was compared when the temperature of the preheating media was different.The results show that increasing the media's temperature can achieve a better preheatin... |
