1. Reminders about flow regimes and velocity profiles

This first paragraph is a reminder of the basic concepts and important models (detailed in the article [J 2 258] ) which are particularly applied in the remainder of this article (calculation of emptying mass flow, residence time distribution (SDD) and segregation issues).

1.1 Mass flow and stack flow

Generally speaking, it is possible to distinguish two main modes of flow within silos:

  • mass flow, where all...
