Numerical Analysis of Minimum Ground Temperature for Heat Extraction in Horizontal Ground Heat Exchangers

Energies, 2021
In this work, numerical simulation calculations were performed to investigate the minimum ground temperature that occurs when extracting thermal energy in a horizontal ground heat exchanger system in the Central European climate.

Deep ground temperatures

, 2000
Some 60 holes drilled for hydrocarbon exploration in the Mackenzie valley afford the opportunity to obtain precise measurements of deep permafrost thicknesses (depth to 0°C) and ground temperatures, and are presented here on maps and graphs. Permafrost thickness is less than 100 m in the Mackenzie Delta, and up to 663 m in the adjoining Tuktoyaktuk ...

Spatial distribution of the snow thermal resistance on the Russian territory and its impact on the ground freezing and thawing

Лëд и снег, 2016
The effect of the snow cover thermal resistance on dynamics of the ground (soil) freezing and thawing is analyzed with the use of numerical modeling. Model calculations show that when heights and densities of snow covers are different, but their thermal ...

Air‐ground temperature coupling and subsurface propagation of annual temperature signals [PDF]

Journal of Geophysical Research: Atmospheres, 2004
Borehole‐based reconstructions of ground surface temperature (GST) have been widely used as indicators of paleoclimate. These reconstructions assume that heat transport within the subsurface is conductive. Climatic interpretations of GST reconstructions also assume that GST is strongly coupled to surface air temperature (SAT) on timescales of decades ...
