| 摘 要： | 管道泄露后引起流体能量迁移,渗流场对温度场产生较大影响.分析了渗流场与土壤温度场的耦合作用,采用有限容积法建立管道泄漏多孔介质流固耦合换热数学模型,界定合理的边界条件,利用SIMPLE算法进行数值求解.得到了管道泄漏前后大地温度场的变化规律.结果表明:管道泄漏后,一定时间内管道附近大地温度场波动明显.随着泄漏时间的延续...

| Abstract: | The pipeline leak can cause fluid energy transfer,and the seepage field has great impact on temperature field.In this paper,coupling effect of seepage field and soil temperature field was analyzed.Heat transfer mathematic model in porous medium on account of fluid-solid coupling effect around pipeline leak points was established by the finite volume method,the reasonable boundary conditions were defined,numerical calculation was carried by SIMPLE numerical algorithm.Change rule of temperature field before a... |
