CFD-DEM investigation on particle clogging in porous media at different scales: From single pore to digital rock

Key Points

• Particle clogging significantly increases as the scale shifts from single pores to digital rock models, impacting flow dynamics.
• The investigation utilizes computational fluid dynamics and discrete element modeling to explore multiple scales of clogging.
• Results show that variations in pore structure contribute to clogging behavior under different flow conditions.
• Findings highlight the importance of understanding particle interactions across scales for improved modeling of porous media.
