Finite‐Size Scaling for the Permeability of Discrete Fracture Networks

open access: yesGeophysical Research Letters, 2023
We formulate a finite‐size scaling hypothesis to predict the global permeability of fracture networks. To validate the hypothesis, numerous discrete fracture networks are generated, and the permeability is numerically calculated. Results suggest that the
