| 摘 要： | 采用Darcy自然对流传换模型分析了同轴管式井下换热器（DCHE）在对流型地热储中的换热物性，在假设井下换热器外壁温度变化与其高度成幂函数关系的基础上，建立了数学模型并得出了相似妥，为其进一步工程应用奠定了较好的理论基础。

| Abstract: | An analysis is made for the heat transfer characteristics of downhole coaxial heat exchanger(DCHE) in convection geothermal reservoir with Darcy's natural convection model,where surface temperature of the DCHE is a power function of depth from the leading edge,and some similarity solutions are obtained.It will be helpful to develop the vertical ground Downhole coaxial heat exchanger. |
