TLDR
In this article, an analysis of the vortex motion in vertical or steeply inclined screw or auger conveyors is presented, which is characterised by the tangential component of the absolute grain velocity being substantially constant with the radial position of a point on the blade.About:

Prediction of screw conveyor performance using the Discrete Element Method (DEM)
Phil Owen,Paul W. Cleary +1 more
TL;DR: In this paper, the Discrete Element Method (DEM) is applied to simulate a single pitch screw conveyor with periodic boundary conditions to predict the performance of screw conveyors in terms of variations of particle speeds, mass flow rate, energy dissipation and power consumption, due to changes in the operating conditions.

DEM study of the flow of cohesive particles in a screw feeder
Qinfu Hou,Kejun Dong,Aibing Yu +2 more
TL;DR: In this article, a numerical model is developed by means of the discrete element method to study the flow of cohesive particles in screw feeders, and a correlation for the prediction of solid flowrate is formulated as a function of the magnitude of cohesive force and the rotational speed of a screw.
Journal ArticleDOI
A Plant-Wide Dynamic Model of a Continuous Pharmaceutical Process
TL;DR: This model is first used to simulate a base case that shows typical limitations in achieving simultaneously high productivity and quality, and the main critical quality attribute considered is the purity of the final product.
