Study on Characteristics and Evolution Process of Rock Fracture Seepage Based on EDEM-FLUENT
In order to study the micro-scale fracture flow process,a three-dimensional single fracture flow model was constructed.The EDEM-FLUENT software was utilized to numerically simulate the fluid-particle interaction in the single fracture structure,enabling visualization of pressure and velocity distribution during the flow process.This study elucidated the correlation between fluid-particle flow characteristics in the permeation process of the single fracture structure.Under pressurized water action,erosion resulting from particle migration induced distinct stages of morphological changes in water flow at the penetrated throat section of the single fracture:initial stage,softening erosion stage,expansion stage,and complete penetration stage.The evolution process of micro-fractures was evaluated based on particle erosion rate,providing a comprehensive depiction of its staged changes characterized by rapid growth-slow-steady trend.
