摘　　要：通过对埋地热力管道周围大地温度场的分析,建立了埋地热力管道泄漏前后的大地温度场的物理和数学模型,给出了合理的热力学及流体力学边界条件,采用FLUENT软件进行埋地热力管道泄漏前稳态温度场的数值模拟.在此基础上分析了埋地热力管道发生裂缝泄漏的二维瞬态温度场的数值模拟,为光纤光栅温度传感器及热红外技术检测热力管道泄漏提供了理论依据.Physical and mathematical models of ground temperature field before and after the leakage of the buried thermal pipeline are set up by analyzing the temperature field,thermodynamics and the hydromechanics boundary condition are given.FLUENT,one of CFD software,is adopted to carry out numerical simulation of the steady temperature field before leakage of the buried thermal energy pipeline.On this basis,numerical simulation of the unsteady temperature field after leakage is carried out,theoretical foundation of examination technology with optical fiber sensor and infrared image in pipeline leakage detection is offered.
