PhD position on numerical simulation of capillary suspensions


Job description

A 4-year PhD position at the University of Twente (UT) is available within an NWO project on numerical simulation of capillary suspensions, called "Next generation materials via controlled capillary suspensions". The position is at the Multi-Scale Mechanics group (MSM) of the department of Thermal and Fluid Engineering (TFE). The offered PhD position is part of a joint research project with the University of Wageningen.

Capillary suspensions feature networks of liquid bridges between particles suspended in two immiscible liquids. This emerging energetically-driven phenomenon has the potential to revolutionize materials design and to quickly push food technology and pharmaceutical industries toward new sustainable development models.

The PhD student will use microscopic numerical methods, namely molecular dynamics (MD) simulations and dissipative particle dynamics (DPD) to build a hybrid all-atom-mesoscale model of capillary suspensions in order to explore their rheological behavior. The goal is to reveal how liquids interact and adsorb on the surface of particles, and expose the multiscale mechanisms behind the formation of liquid bridges and the formation of meso/macro-structures. Experiments will be performed in collaboration with the University of Wageningen to validate the numerical models.

Your profile

We welcome applications from candidates with a MSc degree or equivalent in physics, material science, chemistry, fluid mechanics or related fields. Knowledge on particulate suspensions, emulsions, or interfacial phenomena is highly appreciated. Experience with numerical simulations (molecular dynamics, DPD or other small scale methods) is advantageous. Proficiency in spoken and written English, with good interpersonal communication skills is a requirement.


You are welcome to contact for any questions you might have: Dr. Ahmed Jarray,, and/or Prof. Stefan Luding, 

Please upload your application, including the following documents, as a *single* PDF file through the button below.

  • A motivation letter, emphasizing your specific interest, qualifications and motivation to apply for this position.
  • A detailed CV including a short summary of your MSc research and contact information of at least two references that may be consulted.
  • MSc grade list.

The application deadline is October 15th, 2020.

A Game-Based assessment will be also part of the selection procedure.
