The numerical diffusion effects appear due to the discretization process of the convective terms of the transport equations. This phenomenon takes place also in the numerical simulation of gas-solid two-phase flows in bubbling fluidized beds (BFB). I

The discrete element method is a method for simulation of a particle system. For the “soft-sphere” mechanism of particle interactions, there are several models for normal contact forces, namely linear spring–dashpot, and non-linear damped Hertz

The focus of this paper is to study the behavior of systems with continuous particle size distributions over a gas-solid flow in a bubbling fluidized bed. A lognormal distribution with particle-size range between 800 micrometers and 900 micrometers w

The purpose of this paper is to analyze the granular material discharge from a hopper. For this study was used the modification of a frictional-kinetic model for the gas-particle flow proposed by Srivastava and Sundaresan [1] (S-S model) and compared
