Solid-liquid Flow Experiment with Real and Artificial Manganese Nodules in Flexible Hoses

摘要

Experiments have been performed to study the differences of the flow characteristics between real and artificial manganese nodules-water mixture and synthetic nodules-water. The results show that the hydraulic gradients of the mixtures were almost identical in the case of both the real and synthetic nodules. However, when the solid volume fraction is high, the hydraulic gradients of the flow of the real manganese nodules were a little lower than those of the artificial ones, because the drag effect is not so apparent.
