Impact of position and production of injection wells on groundwater flow and temperature field with groundwater source heat pump

A three dimensional numerical model which couples groundwater flow and heat transfer was developed to simulate changes of groundwater flow field and groundwater temperature field after energy mining for various positioning of multiple(clustered vs interspersed) production and injection wells.The simulation results indicate that the incidence of groundwater flow and temperature are large in the clustered production and injection wells than that in the interspersed form.The interspersed form has higher efficiency than the clustered from.
