DEPOSITION VELOCITIES, TRANSITION VELOCITIES, AND SPATIAL DISTRIBUTION OF SOLIDS IN SLURRY PIPELINES

Deposition velocities are calculated using various Froude number correlations; these are transition velocities between homogeneous flow (uniform solids distribution across the pipe) and heterogeneous flow (poor solids distribution). The degree of heterogeneity which can be tolerated in a pipeline is dependent upon the specific application. Operationg data for long distance pipelines transporting coal, limestone, and magnetite are compared with a typical pipeline for transporting gravel; although all four systems are in turbulent flow as indicated by the bulk Reynolds numbers, the gravel line shows very poor solids distribution while all the other lines show good suspension.
