摘要：

Natural convection in porous medium from downhole coaxial heat exchangers was numerically analyzed. The variable well wall temperature was locally linearized by discretization along the well. Darcy's law and Boussinesq approximation were given in the analysis. The effects of some porous medium parameters on the heat output of the heat exchangers were found.
