Enschede, Overijssel, Nederland University of Twente Voltijd

We are seeking a highly skilled PhD researcher to join our team at the University of Twente, Netherlands. The ideal candidate will have a strong background in granular physics, geomechanics, computer modelling and the discrete element methods (DEM).

This project is part of the EU funded Marie Curie Doctoral Network POSEIDON – Improve offshore infrastructure resilience against geohazards towards a changing climate.

Background and Aim:

The prediction of submarine granular flows, from initiation to run-out, is a significant scientific and practical challenge. Our research aims to develop a hydro-micromechanical model of realistic granular soils using fully-resolved direct numerical simulation techniques.

We aim to understand the role of grain morphology and mesostructure in the avalanching and resting processes during submarine landslides, at various overpressure conditions.

Objectives:

  • Apply an existing LBM-DEM numerical model to simulate the collapse of dense/loose granular masses over an inclined plane subjected to sudden increase of pore pressure;
  • Incorporate realistic particle shapes in the LBM-DEM model and study the effect of grain morphology on hydromechanical behaviour;
  • Compare and validate the simulations with laboratory experiments on granular–liquid mixtures;
  • Coarse grain particle scale information into continuum fields and understand mass/momentum transfer and energy dissipation mechanisms.

Expected Results:

  • A novel hydro-micromechanical numerical tool for modelling saturated granular masses in submarine landslides;
  • A deep understanding of the interplay between structural properties and pore water pressure on saturated granular flows.

Your Profile:

  • Obtained a MSc degree in a relevant field such as civil engineering, mechanical engineering, computational physics, applied mathematics or related areas;
  • Good knowledge of fluid-coupled particulate systems in slow and/or fast motion;
  • Solid programming skills in C/C++, Fortran, Python or equivalent;
  • Experience with the discrete element method or other particle-based numerical methods would be advantageous;
  • You are an excellent teammate, able to collaborate intensively with industrial and academic parties;
  • An appropriate qualification in the English Language together with excellent communication and organizational skills.

Our Offer:

  • We offer a full-time 4-year PhD-position, with excellent mentorship and a stimulating research environment;
  • Collaborations with a dedicated, dynamic research team and external parties from several European countries involved in the POSEIDON project;
  • The gross monthly salary will be approximately €3,200, increasing each year up to €4,000 in the fourth year; Salary and associated conditions are in accordance with the collective labour agreement for Dutch universities;
  • You will have a minimum of 232 leave hours in case of full-time employment based on a formal workweek of 38 hours;
  • We offer excellent fringe benefits including a holiday allowance of 8% of the gross annual salary, an end-of-year bonus of 8.3%, a solid pension scheme, free access to sports facilities and a family-friendly institution that offers parental leave.
