Fig. 8From: The effect of spatial aperture variations on the thermal performance of discretely fractured geothermal reservoirsHistogram of the thermal performance of the two fracture system when \(L/(2R)=0.4\), \(\sigma _h/\left\langle w \right\rangle =0.25\), and \(\zeta =0.8\). A Gaussian fit results in a mean and standard deviation of 0.751 and 0.0625, respectivelyBack to article page
