PetraSim – A shallow geothermal model with pipe flow

February 3, 2014
We recently had a customer request for some help with a shallow geothermal model. I thought it would be interesting to show one approach to simulating fluid flow in tubes (pipes) with heat conduction into the surrounding soil. When I first saw this problem, I thought that PetraSim (TOUGH2) might not be the best code for the solution. The pipe geometry would need to be approximated and if conduction is the dominant mechanism in the soil, there might be other codes that could do a good job. However, PetraSim (TOUGH2) does offer some unique advantages to simulate complex heat transfer in the soil, including the potential heat transport due to groundwater flow.  Read More...
