Abstract

MEDINA, A. et al. On the mass flow rate from silos with lateral exit holes. Rev. mex. fis. [online]. 2013, vol.59, n.4, pp.287-291. ISSN 0035-001X.

The mass flow rate, ṁ, associated with the lateral outflow of dry, cohesionless granular material through circular orifices of diameter D made in vertical walls of silos was measured experimentally in order to determine also the influence of the wall thickness of the silo, w. Geometrical arguments, based on the outflow happening, are given in order to have a general correlation forṁ embracing both quantities, D and w. The angle of repose appears to be an important characterization factor in these kinds of flows.

Keywords : Granular systems; granular flow; static sandpiles.
