This work analyzes influence of anisotropy of anisotropic soil on the processes of heat transfer by ground heat exchangers used in ground-coupled heat pump systems. First, this paper uses the heat-source theory to develop several explicit exact solutions for heat conduction in anisotropic...

Assessment of potential use of ground-coupled heat pump (GCHP) system in regional scale is important to promote its growth. Groundwater flow system and subsurface temperature distribution of Tsugaru Plain were comprehended by developing 3D numerical model. In absence of measured hydrological and...

A simplified three-dimensional finite difference model for a single (cylindrical energy pile) CEP was developed. The present model was first verified with an analytical solution based on the special case that the material inside and outside the CEP had the same thermal properties. For the case...

It is well known that the linear electrical response of periodic composites with a microstructure that has sufficiently high symmetry is isotropic. I.e., the macroscopic conductivity or permittivity of such a system, in the absence of an external magnetic field, is a scalar quantity. This is the...

This paper presents an experimental and numerical study on evaluation of thermal response and performance of prototype precast-high strength concrete (PHC) energy pile. Short-term field thermal response tests (TRTs) were conducted for the PHC energy piles installed in partially saturated...

Novel methods are sought to provide greater efficiency of the installation of ground heat exchangers for GSHPs (ground source heat pumps) in domestic buildings. An economically viable option is to utilise concrete foundation piles as ground heat exchangers. The objective of this study is to...
