An Alogrithm for Numerical Simulation of Double-well GWHP System and It's Engineering Application

摘要

To get further insight of the long-term coupled operation of GWHP system, the understanding of the heat and flow transport process in the local aquifer is required. An algorithm is proposed and realized based on the re-coding of HST3D, a 3-D finite-difference program by USGS, to study the long-term operation of double-well GWHP system. A case is selected to demonstrate the algorithm. The 10-year well water temperature and heat pump power-consumption under different well spacing of the model system is given.
