Fig. 4From: The effect of spatial aperture variations on the thermal performance of discretely fractured geothermal reservoirsStandard deviation of the dimensionless production temperature \(\sigma _{\Theta }\) for the ensemble of fracture realizations as a function of dimensionless standard deviation of the aperture \(\sigma _h/\left\langle w \right\rangle\) when \(\zeta =0.8\) and \(L/(2R)=0.4\). The production end time of interest is when the dimensionless production temperature \(\Theta _p\) of the base case (no aperture variations) reaches 0.8. A linear fit is also shownBack to article page
