Abstract

This research forms part of the EU Interreg IVB project Inners, http://inners.eu/,
Inners’ aim is to improve understanding of the energy balance within the urban
water cycle. The primary aim of this part of the project is to predict heat fluxes in
underground pipes. This paper describes the work that has been carried out to
model the influence of ground water and infiltrating storm water on the thermal
conductivity between a buried pipe and the surrounding soil. Heat transfer along a
pipe and in radial direction between soil, water and concrete in steady state
conditions was modelled, taking into account the effect of ground water on the soil
thermal conductivity. Preliminary laboratory tests showed considerable increase in
thermal conductivity when soil is saturated. The model presented was calibrated
using experimental data collected at the University of Bradford.
