Ph.D. Position Heterogeneous Multi-scale Methods for Granular Flows

Summary: Ph.D. Position
Heterogeneous Multi-scale Methods for Granular Flows
Four year position with a starting salary of approx. 24,000 euro per annum
Joint position between
Numerical Analysis and Computational Mechanics group (Department of Applied Mathematics)
Multi-scale Mechanics group (Department of Mechanical Engineering)
University of Twente, Enschede, The Netherlands.
The Research Project
Dry granular flows will be investigated on inclined channels with local constrictions and obstacles. The effects of
polydisperity and non-uniform shape of the particles will be studied for both rotating and non-rotating situations.
The main challenges in the modeling of these flows is understanding the effect of rotation, particle segregation and
how to deal with the co-existence of rapid and slow regimes.
This project will focus on developing a heterogeneous multiscale model, coupling macroscale continuum with
microscale discrete particle models. The coupling will be done at selective regions in space and time thus reducing
computational expense and allowing simulation of the complex granular flows under study.
In a sister project, experiments of these flow configurations will be carried out and an exchange of laboratory
data and numerical models will mutually stimulate both projects. Additionally, this project will be run in close
collaboration with an industrial partner Corus allowing access to large-scale real industry complex granular flows.
