Influences of connectivity and conductivity on nonlinear flow behaviours through three-dimension discrete fracture networks

摘要: Abstract A numerical procedure about nonlinear flow in three-dimension discrete fracture networks was developed by solving the Reynolds equation and Forchheimer using Galerkin method. The simulation results of three intersecting models were compared with experimental data a good agreement observed. Based on further applications model to consideration Barton’s Chen’s empirical model, it found that fluid flows could be appropriately described equation. smoother surfaces greater connectivity network are, lower hydraulic gradient for onset is.
