Figure 11From: Thermal response test for shallow geothermal applications: a probabilistic analysis approach Borehole thermal resistance and ground volumetric heat capacity relationship. Only the couple of values falling inside an interval of admissible min-max values can be considered for conditional estimation. A validity area is identified: (a) whole curve inside and outside limit area; (b) zoom on the validity area and focus on optimal value obtained by conditional estimation.Back to article page
