格子ボルツマン法と個別要素法を用いた多孔質体内の粒子輸送が浸透率に与える影響の検討
Particle transport with fluid flow in porous media is one of important problems in various engineering fields. The migration and sedimentation of micro particles through porous media affect strongly the hydraulic characteristics. The grout injection is performed to reduce the permeability of rock in...

Particle transport with fluid flow in porous media is one of important problems in various engineering fields. The migration and sedimentation of micro particles through porous media affect strongly the hydraulic characteristics. The grout injection is performed to reduce the permeability of rock in civil engineering. In resource engineering, the decline of oil production might be due to the blockage of pore space caused by the asphaltene deposition in oil reservoir. Also, the transport of micro particles with water and gas flow could cause the production decrease in methane hydrate development.This paper presents the simulation study of particle transport in porous media to understand the migration and sedimentation process of micro particles. In this study, we use a numerical simulation method based on the micromechanical fluid-particle system that couples the lattice-Boltzmann method (LBM) and the distinct element method (DEM) . LBM is known to be a suitable technique for simulating fluid flow in complex and time-varying geometries with boundaries. On the other hand, DEM has attracted much attention among many researchers as a useful simulation technique for large deformation problems.
