TL;DR: In this paper, the authors provide a critical review of the analysis of heat transfer by borehole and foundation pile ground heat exchangers with an emphasis on different analytical models, including heat-source models, short-time models, models for energy piles, in situ thermal-response tests, indoor sandbox experiments, and parameter estimation as an inverse problem.

TL;DR: In this paper, a new approach to modeling heat transfer by ground heat exchangers, involving unsteady heat conduction in composite media together with complex geometry, is presented, where analytical solutions for continuous line and cylindrical-surface sources are developed based on Jaeger's instantaneous line-source solution for composite media.

TL;DR: In this article, the downward and upward channels of U-shaped tubes (not the borehole) are approximated as line sources or sinks of heat placed in a composite medium, which can account for not only the influence of the heat capacity of grouting material but also the difference between properties of soil and grout.

TL;DR: In this article, the authors analyzed the influence of anisotropy on the processes of heat transfer by ground heat exchangers used in ground-coupled heat pump systems.

TL;DR: The utilization of recyclable Cu-hs provides a cost-effective and environmentally friendly method for removing mercury from industrial flue gas.
