Information

Partial model to implement models simulating the thermal and fluid behaviour of a borehole segment.

The thermodynamic properties of the fluid circulating in the borehole are calculated as protected parameters in this partial model: c_p (cpMed), k (kMed) and μ (muMed). Additionally, the following parameters are already declared as protected parameters and thus do not need to be declared in models which extend this partial model:

• Rgb_val (Thermal resistance between grout zone and borehole wall)
• RCondGro_val (Thermal resistance between pipe wall and capacity in grout)
• x (Grout capacity location)
