Borehole heat exchanger: modeling validation and system parameters evaluation
Date Issued
2012
Abstract
The development and validation of a numerical model for the simulation of energy flows and temperature changes in a U-tube
borehole heat exchanger is presented. The FlexPDE software package is employed to solve the time-dependent convection-diffusion
equation that models the resulting boundary value problem. The model is validated with experimental data and is used to study how
various parameters like the U-tube diameter, the ground thermal conductivity and specific heat, affect the exchanger temperature.
