Abstract
The present work consists in the characterization of dry granular flows through sudden constrictions during the mechanical clogging. The experimental tests of dry granular flows were performed in a 1.5 m length facility with a slope of 20-degrees, trapped through a vertical gap, with twice the size of the particles diameter, adjacent to the side wall simulating slit dam conditions. This characterization was based on the analysis of the mean velocities and granular temperatures in a particular region of the chute, specifically, near the slit. This work is aimed at understanding what processes lead to the mechanical clogging and how phase transitions occur in the granular system, with emphasys on the liquid - solid transition.
