Fig. 4: Static features of the system.
From: On the dual effect of obstacles in preventing silo clogging in 2D
a Example of the temporal evolution of the kinetic energy of the grains in the whole recorded region (above the orifice) for the quasi-static regime. Red circles indicate the moments at which the fabric tensor is analyzed. b–e Maps of the horizontal fxx and vertical fzz components of the fabric tensor averaged over around 40 different configurations. The results correspond to a silo with an orifice size of D = 1.53cm without obstacle (top row panels) and with it (bottom row panels). f, g Corresponding maps of the rescaled difference between the horizontal and vertical components of the contact fabric tensor (fxx − fzz)/(fxx + fzz).
