Flow Behavior of Coarse-Grained Slurries in Pipes

摘要

The present paper describes the experimental investigation of modelrncoarse-grained slurry on a re-circulation pipe loop with smoothrnstainless steel pipes. Graded pebble gravel and glass balls were used asrna model for poly-metallic nodules, and very fine glass beads as a modelrnfor fine-grained sand. The investigation was focused on evaluating therneffect of slurry velocity and particle concentration on pressure dropsrnand the slurry flow behavior in the turbulent regime. Also the effect ofrnfine-grained particle addition on slurry behavior is described.
