Both unresolved and resolved methods have found widespread application in various fields such as fluidized bed simulation, erosion studies, and sand production analysis. The coupling of DEM and CFD has proven to be a valuable tool for understanding the intric

The fluid mesh, permeability, and flow force are updated at predetermined intervals to ensure accuracy and consistency in the simulation. The program is terminated when the total number of steps reaches a predetermined limit. The simulation results present some new

The example problem illustrate the effect of discrete fracture network on hydraulic fracture propagation and reservoir stimulation.

Einführende Bemerkungen zum FBSd data. The energy budget analysis indicates that the aseismic deformation consumes a major part of the energy. The simulated fault shear displacement is also consistent with the casing deformation measured in the field. The model is also used to investigate the impact of possible operational change

The magnitude of the breakdown pressure is associated with the level of fracture complexity generated before the breakdown. Despite the variation of breakdown pressure for different perforation models, both the init

In this model, perforation friction, geological factor such as stress difference between adjacent clusters, and filtration of fracturing fluid are considered. The numerical results are compared with field data (i.e., injection pressure and cluster efficiency) obtained from the fract

Introduction to the Discrete Element Method (DEM),offers greater computational speed in implementation of the discrete element method without sacrifice of important mechanics. The fluid mechanics concepts important and used in coupled hydro-mechanical processes in fractured and granular media are presented at the end of the chapter.

Discrete Element Modeling of Hydraulic Fracturing, the coupled DEM-PNM model can effectively analyze the intricate fracturing behavior associated with hydraulic fracturing in naturally fractured rock masses and dense granular media. The numerical analysis provides valuable insights into the mechanisms underlying strong hydro-mechanical coupling pro
