Numerical simulation device for the transport of geothermal heat with forced circulation of media

This article deals with the acquiring of low-potential energy with vertical ground heat exchangers and gravity U-tube. These two systems are a part of the device (simulator) for low-potential heat transport through the phase changes in the vaporization and the condensation part of the tube at temperatures below 0 °C. So, the device thus allows a development of research activities during the verification of the technological production of a heat pipe that is suitable for the utilization of terrestrial heat at low temperature in a laboratory environment. The individual components of the device allow a research of thermo-kinetic heat transport parameters and realistic modeling of a heat flow from the rock into the heat transfer fluid.
