... distributions. In this paper, we perform a complete analysis of 3D fracture intersections distribution of various DFN models and investigate how it can be related to the 2D distribution of intersecting virtual outcrops. The DFN models are either fully random (with no correlation between fractures) or defined...

A usual method is to define 3D Discrete Fracture Network (DFN) models to represent the geological environment. This consists in combining various data on fracture geometrical properties (density, size and orientation...

The results showed that the role of fracture surface roughness in macroscopic fluid flow and heat transfer in fractured rocks is critical, in terms of reducing total flow rate and increasing thermal breakthrough time. Macroscopic fluid flow and heat transfer in different realizations of DFN models can...
