Table 2 Specific heat load (q), effective thermal conductivity (λeff), Darcy velocity (vf) and hydraulic conductivity (k) for the different approaches of heat load determination: qR=fix assuming constant electrical resistance, average qave and adjusted qadj
From: Evaluating an enhanced thermal response test (ETRT) with high groundwater flow
Specific heat load | q [W m−1] | λeff [W m−1 K−1] | vf [m d−1]a | k × 10–3 [m s−1]b |
|---|---|---|---|---|
qR=fix | 22.8 (± 0.8) | 5.1 (± 0.2) | 0.68 (± 0.18) | 3.9 (± 1.0) |
qave | 20.9 (± 0.8) | 4.6 (± 0.2) | 0.57 (± 0.16) | 3.2 (± 0.9) |
qadj | 20.2 (± 1.1) | 4.5 (± 0.2) | 0.53 (± 0.15) | 3.1 (± 0.9) |
