In most of the world, borehole heat exchangers used with closed-loop ground source heat pump systems are backfilled with a low permeability grout to prevent water contamination. However, in Scandinavian countries, a different approach is taken – the borehole is sealed at the top and cased down to solid bedrock. The borehole then naturally fills with groundwater in the annular space between the U-t
This paper proposes a new frequency domain method to model the heat transfer between the injected/extracted heat and the temperature of the fluid exiting a borehole heat exchanger. The method is based on in situ measurements and focuses particularly on the short-term borehole heat transfer. It uses a rational function of the Warburg variable in the Laplace domain to model the borehole heat transfe
The courtroom work of defence lawyers has received surprisingly little sociological attention leading to the question: how do defence lawyers represent their client beyond the hard paragraphs of the law? By studying this phenomenon in a context where the scope for expressive gestures is limited, it is possible to gain a greater understanding into the often subtle ways in which legal teamwork is pe
