A mechanistic model has been developed to predict settling velocity in a vertical pipe, and a finite-difference model has been developed to predict particle sedimentation rates. Experiments have been conducted in a vertical pipe filled with water or white oil to observe the different sedimentation regimes and measure the particle sedimentation rates for model verification. Particles used in the experiments were sand and glass beads. A two-pipe apparatus and a one-pipe apparatus were used. Several sedimentation phenomena were observed including, dilute particle settling, clustered settling, hindered settling, and particle bridging phenomenon. Good agreement in rate of sand bed buildup was found between the model and data in the one-pipe apparatus.
