Finite element analysis under different boundary conditions of the filling of cylindrical steel silos having an eccentric hopper

Numerical Investigation on Granular Flow from a Wedge‐Shaped Feed Hopper Using the Discrete Element Method

“…Hoppers are commonly used in pharmaceutical, food, and chemical industries to store and transport granular materials [1,2]. In the process of granulation production, the wedgeshaped feed hoppers are more widely applied due to physical space constraints and the need to interface with other processing equipment [3].…”

Finite element investigation of the flow and stress patterns in conical hopper during discharge

“…FEM associated with elastoplastic constitutive theories can give satisfactory predictions of the internal stress and wall pressure in hoppers (Ooi and Rotter, 1990;Rotter et al, 1998;Goodey et al, 2003Goodey et al, , 2006Goodey and Brown, 2004;Vidal et al, 2006Vidal et al, , 2008Ding et al, 2013). However, its application to reproduce the flow conditions of granular material is usually not easy Sanad et al, 2001;Tejchman and Klisiński, 2001) and requires some particular schemes or treatments such as the re-meshing and re-zoning scheme (Sanad et al, 2001), adaptive meshing technique (Yang et al, 2011), viscoplastic granular fluid models (Haussler and Eibl, 1984;Karlsson et al, 1998;Elaskar et al, 2000;Böhrnsen et al, 2004), smoothed particle hydrodynamics (SPH) method (Sugino and Yuu, 2002), and material point method (MPM) (Wieckowski et al, 1999).…”

A simplified 3 D.O.F. model of A FEM model for seismic analysis of a silo containing elastic material accounting for soil–structure interaction

“…It is suggested, however, that not enough research currently exists to represent the issues fully. Contrary to this, there are a lot of studies about the effects of filling, discharging and/or the flow of bulk material when it comes to silos [2][3][4][5][6][7][8][9][10]. However, little information can be found about the seismic behavior of cylindrical silos.…”
