| Abstract | Someof the factors influencing the performance of Downhole Heat Exchangers (DHEs) in shallow hot water wells were investigated using a model which has been developed at the University of Two different materials, copper and PVC, were used to construct two otherwise identical U-tube DHEs, which were tested over a range of DHE flow and cross flow rates. During most tests a PVC convection promoter pipe was in well, to allow a bulk circulation of the well fluid. Somecomparisonsare made to results obtained during full scale testing in a shallow Rotorua well. |
