Cálculo de ar induzido pela queda livre de materiais granulares via CFD

Abstract

The proposal of the work consists of presenting an analysis method via ANSYS-Fluent using the DDPM tool (Dense Discrete Phase Model) of the integrated Eulerian multiphase model, a better understanding of the flow of granulated material with the adjacent induced air due to the drag provided by the free-falling particles, which result in the generation and propagation of dust, avoid simulations with materials where particle density and diameters are variable. The use of this analysis tool will make it possible to improve and improve de dusting projects in industries that work with granular materials that emit dust. The simulations carried out were compared with other computational methods and practical experiments, in addition to previous theoretical formulas.
