Effect of a Inclined Tube Shape on the Settling Rate

Abstract

Settling enhancement effect in a inclined tube was studied experimentally with calcium carbonate slurries. The model proposed in this study, which has a wedge-shaped layer of clear liquid developed at the upper surface of the inclined plate, can explain the difference between vertical and inclined settling velocities. It was shown that the inclined settling rate increases with increasing inclined settling enhancement factor in consideration of inclined tube cross-section shape.
