Fig. 11From: The effect of spatial aperture variations on the thermal performance of discretely fractured geothermal reservoirsThe standard deviation of the dimensionless production temperature \(\sigma _{\theta }\) as a function of the standard deviation of the fraction flow split \(\sigma _{\phi }\) when \(L/(2R) = 0.4\) and \(\zeta =0.8\). A linear fit is also shownBack to article page
