Discrete numerical simulation of sheared particle flow in a vertical sandwich belt conveyor

In this study, an improved sandwich conveying numerical simulation model was used to analyse the influence of five factors on the conveying efficiency of a vertical sandwich belt conveyor. The mass flow rate of the model was verified using a test model. The results showed that the mass flow rate and shear depth increased as the belt speed increased. Additionally, the particle velocity tends to decrease with increase in depth, and increasing the pressing force increased the contact force chain. Furthermore, the contact force chain remained constant in the vertical direction. The strength of the contact force chain was maximised when the moisture content was 20–30%.

期刊介绍： GENERAL OBJECTIVES: Computational Particle Mechanics (CPM) is a quarterly journal with the goal of publishing full-length original articles addressing the modeling and simulation of systems involving particles and particle methods. The goal is to enhance communication among researchers in the applied sciences who use "particles'''' in one form or another in their research. SPECIFIC OBJECTIVES: Particle-based materials and numerical methods have become wide-spread in the natural and applied sciences, engineering, biology. The term "particle methods/mechanics'''' has now come to imply several different things to researchers in the 21st century, including: (a) Particles as a physical unit in granular media, particulate ﬂows, plasmas, swarms, etc., (b) Particles representing material phases in continua at the meso-, micro-and nano-scale and (c) Particles as a discretization unit in continua and discontinua in numerical methods such as Discrete Element Methods (DEM), Particle Finite Element Methods (PFEM), Molecular Dynamics (MD), and Smoothed Particle Hydrodynamics (SPH), to name a few.
