Abstract

This paper presents the preliminary simulation study of a typical centrifuge currently produced by Gamma Meccanica. The objective of this study is to evaluate the behaviour of the centrifuge using moving particle simulation and discrete element method (MPS-DEM) simulation techniques with Particleworks 7.2.1 to gain a better understanding of phenomena that are impossible to monitor experimentally.

Qualitative and quantitative results, such as the distribution of water and plastic particles within the centrifuge, will be compared to identify key factors for further analysis and improvement in future studies. Particular phenomena like blade erosion due to particle impact will be used for qualitative validation of the model. The presented model and results formed part of a feasibility analysis of different rotor configurations. The varying distribution of the water and particles enabled observations about the performance of different rotor geometries in terms of energy efficiency and moisture in the final product. The results of the numerical comparison will be very useful for future improvements not presented in this article.

CASE STUDY

The roller coaster

A design challenge combining excitement and rigour

A fascinating article on the origin, history, and evolution of roller coasters from their earliest prototypes in Russia in the 16th century on the banks of the Neva River of St. Petersburg, and then dives into detail on how numerical simulation of roller coasters works to ensure their success both as entertainment and from a safety perspective for users and operators.
