The University of Luxembourg aspires to be one of Europe’s most highly regarded universities with a distinctly international and interdisciplinary character .
It fosters the cross-fertilisation of research and teaching , is relevant to its country, is known worldwide for its research and teaching in targeted areas, and is establishing itself as an innovative model for contemporary European Higher Education.
The University s core asset is its well-connected world-class academic staff which will attract the most motivated, talented and creative students and young researchers who will learn to enjoy taking up challenges and develop into visionary thinkers able to shape society.
The Faculty of Science, Technology and Medicine (FSTM) contributes multidisciplinary expertise in the fields of Mathematics , Physics , Engineering , Computer Science , Life Sciences and Medicine .
Through its dual mission of teaching and research, the FSTM seeks to generate and disseminate knowledge and train new generations of responsible citizens, in order to better understand, explain and advance society and environment we live in.
The University of Luxembourg within its multi-disciplinary and -cultural environment seeks a PhD collaborator for participating in an advanced grant at the interface of academia and industry.
The objective is to investigate and model macroscopic concrete flow behaviour with regard to both, the influence of the interface layer at the wall and the particle interactions, being the key issues for fundamental modelling of concrete rheology.
Therefore, the aim of the present project is the investigation and modelling of time- and shear-dependent microstructure (disperse properties) and rheological properties of cementitious suspensions subjected to shear applying the Immersed Boundary Method (IBM).
In this project, the addressed key issues are
Only a scale-bridging approach from the micro-scale (dparticleparticle 4 mm) to the macro-scale (dparticle>
4 mm) enables to adequately address these issues and herewith achieve the goal to model and predict the flow behaviour. Here, suspensions relevant to the construction industry, i.
e. cement paste and concrete containing super-plasticizer, are considered in this project.
