【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特性 ,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解 ,为其进一步工程应用奠定了较好的理论基础。更多还原

【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.更多还原
