Analysis of Dust Distribution in Silo during Axial Filling using Computational Fluid Dynamics: Assessment on Dust Explosion Likelihood

In this study, the dust distribution in a silo during axial filling was modelled using a commercial computational fluid dynamics (CFD) code. The work focused on the dust concentration distribution in the silo, for evaluating the likelihood of a dust explosion in the silo. The simulation was conducte...
