The University of Twente seeks a full-time PhD researcher with research interests in granular physics, continuum mechanics, computer modelling, and the discrete element methods (DEM) to join the University of Twente (Netherlands) on microscale modelling and constitutive relations for wet granular materials. This project aims to develop a meso-particle model to simulate wet systems for all degrees of saturation.

This project is part of the EU funded Marie Curie Initial Training Network TUSAIL– Training in Upscaling Particle Systems: Advancing Industry across Length-scales (www.tusail.eu). The overarching objective of TUSAIL is to develop, apply and validate three novel modelling methodologies in the upscaling of industrial particulate processes. TUSAIL will train 15 researchers within a collaborative multidisciplinary and inter-sectorial network involving six university partners and five significant industries across Europe.
Methods exist to satisfactorily simulate fully saturated particle systems and systems in the pendular regime with independent liquid bridges. In the last case, the liquid provides an additional force between pairs of (meso-)particles. The challenge lies in the intermediate liquid content range. The method will be applied to macro-scale processes, e.g. agglomeration, granulation and mixing, where the size/type of particles evolves due to the fluid.
Specific objectives are:
- Establish and validate contact models between DEM particles and solid-fluid coupling algorithms to describe varying amounts of liquid (0% to 100%) in granular systems;
- Derive the relation between microstructure and liquid content to be included in the up-scaled meso-particles and wet-flow rheology.
Apply the developed methodologies to selected wet industrial particle processes (granulation, mixing).
Expected output of the project are:
- Micro-scale DEM simulation data and proposed contact laws in the pendular/funicular/capillary regimes;
- Meso-particle model for agglomeration, breakage, segregation and mixing.
Laboratory tests for large scale validation will be performed in collaboration with our partners Johnson Matthey (UK), that will host the researcher for secondment. Further comparison of the upscaled numerical model, this time with industrial scale data, will be conducted under the supervision of our partners during a secondment at Nestle (CHF).
The deadline for applications is March 15, 2021
As an ideal candidate:
- You have an MSc degree or a first or upper second class honours degree in a relevant field such as physics, mechanical engineering, civil engineering, chemical engineering, applied mathematics, materials science or related areas;
- You are interested to learn and contribute to new technologies for particle technology application;
- Knowledge in DEM modelling or numerical methods in general and a good understanding of particle technology or granular physics would be advantageous;
- You are an excellent teammate, able to collaborate intensively with industrial and academic parties in regular meetings and work visits;
- Furthermore, an appropriate qualification in the English Language, together with excellent communication and organizational skills, are required.
This fellowship is offered in the context of a Marie Curie Initial Training Network, and transnational mobility is a critical element of eligibility. Therefore your eligibility for the post is determined by Marie Curie terms and conditions. Researchers may be either EU citizens or from outside the EU (subject to relevant immigration formalities), but applications will only be accepted from candidates who must not have resided or carried out their main activity (work, studies, etc.) in the Netherlands for more than 12 months in the three years immediately prior to the date of selection by the host institution (short stays such as holidays are not taken into account). Check the Eligibility Criteria carefully on the TUSAIL website https://tusail.eu/projects.eligibility.
This position is for four years. In addition to their scientific projects, all fellows will benefit from further continuing education, which includes secondments and short visits to partners in the TUSAIL network, a wide range of training activities, workshops, dedicated sessions at international meetings to foster scientific and transferable skills for the Jobs of Tomorrow.
The salary in the Netherlands ranges from EUR 2.395,- (1st year) to EUR 3.061,- (4th year) per month, plus holiday allowance (8%) and end-of-year bonus (8.3%), in accordance with the Dutch Collective Labour Agreement. Further information can be found at http://www.utwente.nl.
The PhD project will be conducted under the supervision of Prof. S Luding and Dr V. Magnanimo at the University of Twente. An Individual Supervisory Committee, including industrial partner, s will guide the candidate during his/her PhD.
For applications, please submit your documents using the ‘Apply now’ button below, including your CV, motivation letter, bachelor and master transcripts, contact details of at least two references who worked closely with you, theses or reports (if available).
Master students who will graduate in the next coming months are welcome to apply. In that case, please provide an overview of the transcripts that are already available.
The intended starting date is September 1, 2021, at the latest.
For more information about the position, you are encouraged to send an e-mail to Dr V. Magnanimo ([email protected]).
The selection procedure is performed by the beneficiaries within TUSAIL project and thus by all partners involved in the project https://tusail.eu/partners.
This means your application is shared amongst the universities under the GDPR terms of data collection. It could be possible that the beneficiaries identify that another position would be more suitable for your background and skills.
