The subsurface thermal regime has been investigated in boreholes from southern Norway.

During the purely conductive 2D thermal modeling, the COMSOL Heat Transfer for Solids interface has been used to simulate heat transfer by heat conduction. COMSOL physics interfaces Heat Transfer in Porous Media and Porous Media and Subsurface Flow/Darcy's Law have been used to carry out a fully coupled thermal modeling with taking into account the advection heat transfer due to groundwater flow.

Results of the modeling of coupled groundwater flow and heat transfer indicate that the advective cooling due to groundwater flow is the important factor for the reduction of temperatures.
