| Abstract: | Based on the analytical solution for a line heat source in an infinite domain with groundwater advection, the influence of the groundwater advection on the heat transfer of geothermal heat exchanger is discussed, including different groundwater flow velocities and different thermal properties. In order to determine whether the groundwater flow factor should be considered in the design of geothermal heat exchanger, Peclet Number is introduced to be a distinguishing term. |
