Abstract

An analytical solution of the steady-state temperature distribution has been derived in a semi-infinite medium with an inclined line-source of finite length. The impacts of geometrical and physical parameters on this heat transfer process have been discussed accordingly. Two characteristic steady-state temperatures of the inclined borehole wall are defined as the middle section representative temperature and the whole-length integral average temperature. Differences between them are evaluated, and concise expressions for both of them are presented for practical engineering applications.

Keywords. ground-coupled heat pump; ground heat exchanger; heat conduction; inclined boreholes
