modelConstantHeatInjection_100Boreholes
Long-term temperature response of a borefield of 100 boreholes
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This validation case simulates a borefield of 100 boreholes on a square 10 by 10 grid.
The heat injection rate in the borefield is constant and equal to
2*pi*kSoi*hBor*nBor. In this case, the borehole wall temperature
variation corresponds to the g-function of the borefield, as evaluated in
Buildings.Fluid.Geothermal.Borefields.BaseClasses.HeatTransfer.ThermalResponseFactors.Validation.GFunction_100boreholes.
