Three Dimensional Numerical Analysis of Fluid Flow through Fractured Rock Core Using X-Ray Computed Tomography

A three dimensional numerical modeling coupled with X-ray Computed Tomography (CT) for fracture flow was applied to<br>fractured granite core samples. One of the samples had an artificial single fracture, and the others had natural multiple<br>fractures. A relationship between CT value and fracture aperture (fracture aperture calibration curve) was obtained by X-ray<br>CT scanning for a fracture aperture calibration standard with varying the aperture from 0.1 to 0.5 mm. As a result, a linear<br>relationship was obtained between CT value and fracture aperture.
