文摘
- •
We model lateral solid mixing using the Eulerian–Eulerian and Eulerian–Lagrangian approaches.
- •
We quantify mixing by means of a lateral dispersion coefficient.
- •
We investigate the influence of simulation dimensionality and frictional stress models on the lateral dispersion coefficients.
- •
We compare the numerical results obtained from the Eulerian–Eulerian and Eulerian–Lagrangian approaches.
