The heat transfer around energy piles with groundwater flow for ground-coupled heat pump has been reported in recent years. However, the combined model was always studied on condition that groundwater flows in a one-dimensional manner. This paper describes a novel mathematical model that explains the heat transfer of energy piles with groundwater of two-dimensional (2D) flow. The analytical solutions of the governing equations are obtained based on the Green function of 2D advection. The characteristics involved in the heat transfer of energy pile when 2D groundwater plays role are investigated. Afterwards, the progressiveness of the new model is highlighted.
