Virtual borehole for thermal response test unit calibration: Test facility and concept development
(International Ground Source Heat Pump Association, 2018)
Precise calculation of the borehole length requires good estimation of the ground thermal conductivity. In practice, the ground thermal conductivity is measured in-situ at a specific location using what is referred to as ...
Hybrid model for generating short-time g-functions
(International Ground Source Heat Pump Association, 2018)
A hybrid numerical/analytical approach is proposed to predict short-time g-functions. Transient heat transfer in the borehole is solved numerically while ground heat transfer is evaluated analytically using the infinite ...
