Fig. 3

Calculated rock temperatures (a, c) and difference between water and rock temperatures (b, d) for snapshots at 1000 s (a, b), close to the end of the injected temperature pulse, and 3000 s (c, d) after the start of the simulation for a flow rate of 7.9 × 10−6 m3/s. A temperature difference of several degrees Celsius between water and rock is sustained during the experiment.
