Suspended Particles Transport and Deposition in Saturated Granular Porous Medium: Particle Size Effects

Lyacine Bennacer; Nasre-Dine Ahfir; Abderrazak Bouanani; Abdellah Alem; Huaqing Wang

An experimental study on the transport and deposition of suspended particles (SP) in a saturated porous medium (calibrated sand) was undertaken. The influence of the size distribution of the SP under different flow rates is explored. To achieve this objective, three populations with different particles size distributions were selected. The median diameter
