This paper proposes a thermal-seepage coupled numerical simulation methodology for the
artificial ground freezing (AGF) process using measured soil freezing characteristic curve …

Two-phase closed thermosyphon (TPCT) has been considered to be an effective measure to
reduce soil temperatures and maintain engineering stabilities in permafrost, but …

Cast-in-place piles are popular foundation forms in permafrost regions. The freezing force at
the pile-soil interface is the main source of bearing capacity, which is quite sensitive to …

Super-long thermosyphons exceeding 100 m are being employed more frequently in
artificial ground freezing (AGF) applications. In this study, we develop a fully-conjugate …

In cold regions, passive thermosyphons are often employed in permafrost protection and
artificial ground freezing (AGF) applications. While passive thermosyphons utilize available …

effective cooling strategy adaptable to different geological and meteorological conditions in …

This study conducts an experimental performance assessment of different gravity-assisted
heat pipes, with length-to-diameter ratios ranging from 50 to 200. Process modelling is …

Building concentric tubes is one of biggest practical challenges in the construction of freeze-
pipes of selective artificial ground freezing (S-AGF) applications for underground mines. In …

Two-phase closed thermosyphons are efficient passive heat transfer devices that have
received substantial attention in ground heat extraction. However, modelling thermal energy …

Permafrost degradation represents a severe challenge for mining operations in Northern
Canada. The foundations of the infrastructures rely on the steadiness of the permafrost …
