The Analysis and Simulation of Granule Concentration Distribution in Cross Section of Spiral Slurry Pipeline

Abstract:

Through the analysis of force acting on granule in slurry spiral flow and movement characteristics of granules, the granule motion equation, the granule size distribution along radial direction, and distribution of granule concentration on cross section of the pipeline were established. By using computer simulation with FLUENT software for granule concentration distribution on cross section in slurry spiral flow of pipeline, the results of simulation revealed that the granule distribution in slurry spiral flow concentrated in peripheral area of cross section of pipeline, the concentration distribution of granule in center of the cross section area was smaller and more uniform, and the concentration of granule was minimum in pipe wall because of the effect of centrifugal force and circumferential velocity acting granules.
