In order to investigate the effect of the shape of an immersed body on the settling velocity of slurry, the experiments were carried out by using several kinds of immersed bodies and CaCo_3-slurry. It was found that the settling velocity increases by immersing a body having many projections in the slurry. The velocity increased with increasing the number of projections on the body, because clear water is produced by settling under the projections. The experimental results were discussed by making some assumptions about settling, and the settling velocity of slurry accelerated by an immersed body was estimated. It was possible to calculate the increase in settling velocity on the assumption that newly produced clear water or liquid under the projections moves upward passing through some slits existing on an immersed body without remixing with slurry.
