Theoretical and experimental investigations of convective heat transfer in geothermal systems are reviewed. The governing equations for such heat transfer in geothermal systems are examined, along with heat transfer in hot-water, water-steam two-phase, and geopressured geothermal systems. Lumped-parameter analyses for predicting averaged reservoir characteristics during production are considered, heat transfer in other geothermal systems (e.g., dry hot rock and magma) is briefly discussed, and investigations of heat transfer in geothermal wellbores are summarized. It is concluded that studies based on the idealization of a geothermal reservoir as a saturation porous medium can provide considerable insight into the physical processes involved.
