| 摘 要： | 埋地热油管道土壤温度场计算是研究热油管道停输再启动及间歇输送的重要组成部分。通过分析埋地热油管道的几何特性建立了热油管道土壤温度场数学模型和求解边界条件。并使用ANSYS有限元软件求解该数学模型。其中,在建立数学模型时,把埋地热油管道土壤温度场简化为二维非稳定传热问题,在求解边界条件中充分考虑了地面温度随季节变化以及土壤温度随深度和季节而变化等诸多因素的影响。通过对土壤温度场一个运行周期的计算可求解出在运行周期内某时刻土壤温度场的温度分布,也可以求解出土壤中任意点在整个运行周期中的温度变化情况。方法简便易行、运行稳定可靠。这些问题的求解为研究热油管道间歇输送过程中确定停输时间以及再启动等问题奠定了基础。

| Abstract: | The calculation for soil temperature field of underground heated pipeline is the important part for research stopping transmission then restarting and intermittently transmission of underground heated pipeline. The mathematical model and boundary condition of soil temperature field is established through analysis geometry model of underground heated pipeline. Then it is solved by finite element method of ANSYS software. Simplifying the temperature field to transient transfer of both - side and the boundary condition relate to the change of atmosphere temperature and the deep of soil. The method is simple and credible. The calculation for soil temperature field of heated pipeline is the foundation of research intermittent transmission and stopping transmission then restarting. |
