Seepage clogging characteristics of rock and soil porous media using LBM-IMB-DEM simulation method
Yantu gongcheng xuebao, 2021 Seepage clogging in rock and soil porous media is essentially the result of the coupling action of seepage and solid particles. A numerical computing platform based on the coupled lattice Boltzmann method-immersed moving boundary-discrete element method (

Mechanism for clogging of microchannels [PDF]
Physical Review E, 2006 We investigate clogging of microchannels at the single-pore level using microfluidic devices as model porous media. The process of clogging is studied at low volume fractions and high flow rates, a technologically important regime. We show that clogging is independent of particle flow rate and volume fraction, indicating that collective effects do not ...

Clogging Time of a Filter [PDF]
Physical Review Letters, 2000 We study the time until a filter becomes clogged due to the trapping of suspended particles as they pass through a porous medium. This trapping progressively impedes and eventually stops the flow of the carrier fluid. We develop a simple description for the pore geometry and the motion of the suspended particles which, together with extreme-value ...
