Abstract
The paper presents an approach to compute and scale-up the wear rate distribution in the cross-section of slurry pipelines. The wear rate is related to the energy dissipated by particle-wall interaction. The velocity and concentration distributions are determined with a multiphase turbulent flow model. The approach was tested for horizontal and inclined pipelines transporting solids with narrow and broad size distributions. A parametric study for a phosphate slurry pipeline is presented.
