How flow of constricted particle suspension differs from hungry sheep herd?

Résumé

When people, animals, or particles are forced through a constriction, they either flow continuously, intermittently, or even not at all when a clogging arch is formed. Herein we focus on non-adhesive colloidal particles in suspension flowing through a constriction. We find that the neck-to-particles size ratio D/d determines the flow regime and is analogous to the sheep-to-door size ratio for a hungry herd, which raises several questions : -Do these two systems behave quantitatively similarly ? -For which neck-to-particles size ratio D/d is the flow intermittent?
