Název v původním jazyce

Evaluation of the 4-Component, settling slurry, pipe friction model against a salt-brine slurry.

Popis výsledku v původním jazyce

A 4-Component model for settling slurry pipe flow has been previously described by Wilson and Sellgren (1) to predict pipeline friction loss (hydraulic gradient) over a range of slurry compositions: from fine to coarse particle size, narrow to broad particle size distribution, and low to high solids concentration. The method applies a weighted average of established pipeline models for various settling slurry flow regimes, according to the volume fraction of solids falling within the applicable size range for each model. Further development of the model was undertaken by Visintainer et al. based on a comprehensive set of laboratory tests in 203 mm (8 inch) and 103 mm (4 inch) pipelines (2), and it was further adapted to the modelling of slurry pump performance derates (3). Subsequent testing in a 489 mm (20 inch) pipeline (4), and with higher density, iron ore solids (5), have extended the range of the model.
