The particle finite element method for transient granular material flow: modelling and validation
(Springer International Publishing AG, 2021-01-01)
The prediction of transient granular material flow is of fundamental industrial importance. The potential of using numerical methods in system design for increasing the operating efficiency of industrial processes involving ...
A comparative assessment of empirical and lattice Boltzmann method-based drag models for simulation of gas–solid flow hydrodynamics in a bubbling fluidized bed
(2017-08-01)
In simulations of fluidized beds using computational fluid dynamics (CFD), the description of gas–solid flow hydrodynamics relies on a drag model to account for the momentum transfer between gas and solid phases. Although ...
Investigation of material flow and thermomechanical behavior during friction stir welding of an AZ31B alloy for threaded and unthreaded pin geometries using computational solid mechanics simulation
(2021-10-01)
In the friction stir welding process, the tool role in the material flow and its thermomechanical behavior is still not entirely understood. Several modeling approaches attempted to explain the material and tool relationship, ...

A Novel Model for Evaluating the Flow of Endodontic Materials Using Micro-computed Tomography
(Elsevier B.V., 2017-05-01)
Introduction: Flow and filling ability are important properties of endodontic materials. The aim of this study was to propose a new technique for evaluating flow using micro computed tomographic (mu CT) imaging. Methods: ...
Gravity flow characterization of fine granular material for Block Caving
(Elsevier Ltd, 2019)
© 2018 Elsevier Ltd Block and Panel Caving are based on the action of gravity for ore breakage and transport, so that material reaches the drawpoint through gravity flow. The study of caved rock flow is of vital importance ...
Sensitivity analysis and parameter estimation of heat transfer and material flow models in Friction Stir Welding
(Universidad Federal de Sao Carlos, 2014-11)
Although numerical models of heat transfer and material flow have contributed to understand the underlying mechanisms of friction stir welding (FSW), there are certain input model parameters that can not be easily determined. ...
Gravity flow and fragmentation modeling in Block Caving
(Universidad de Chile, 2022)
In block caving, the behavior of gravity flow is fundamental in mine design and pla nning. However, the great number of variables that influence this large scale phenomenon are difficult to study directly in the field. ...
