Eulerian–Lagrangian modeling of turbulent liquid–solid slurries in horizontal pipes.

Highlights: [•] The flow organizes into three distinct layers controlled by the two-phase dynamics. [•] Strong segregation in particle size with non-monotonic behavior along vertical axis. [•] Gradient-diffusion model for the vertical drift velocity matched simulation results. [•] Modeling constants for homogeneous gravity-driven flows were computed. [Copyright &y& Elsevier]
