CFD modelling of two-phase flows

At present:


The University of Twente is an entrepreneurial research university. It was founded in 1961 and offers education and research in areas ranging from public policy studies and applied physics to biomedical technology. The University has approximately 2700 employees and 8000 MSc and BSc students and is the Netherlands' only campus university.

The chair of Engineering Fluid Dynamics chair of the Faculty of Engineering Technology (CTW) is embedded in the interdisciplinary Spearhead Institute of the University of Twente IMPACT (Institute of Mechanics, Processes and Control Twente). More information about this chair can be found on: ( More information about IMPACT can be found on ( and in the Dutch Research School for Fluid Mechanics, the J.M. Burgers Centre (

In this group there is a postion for a

PhD reseacher on a project called:

CFD modelling of two-phase flows in high-concentration dredging mixtures


This project is financially supported by SenterNovem. It is a collaborative project involving IHC (manufacturer of dredging equipment) and TU Delft.

The project:

The objective of the 4-year research project is to develop Computational Fluid Dynamics methods that are capable of predicting the complex flows in dredging equipment. This method will focus on the high-concentration regime that is typically appropriate for such equipment. Using this CFD method, existing dredging equipment can be redesigned and optimized.

The research task consists, amongst others, of the following items:

• Measurements on the mechanical behaviour of sand-water mixtures at high-volume concentrations

• Formulation of constitutive relations for sand-water mixtures that describe the mechanical behaviour of the mixtures at high-volume concentrations

• Development and implementation of a CFD-method for the sand-water mixtures, employing the formulated constitutive relations

• Applying the developed CFD-method to a representative dredging flow


An M.Sc. or comparable degree in mechanical engineering, civil engineering, aerospace engineering or applied physics with demonstrated abilities in the fields of fluid mechanics, CFD and experimental techniques; Good command of the English language. Ability to perform research work in a team.


We offer you a temporary position for a period of four years. Gross monthly salary for the PhD position ranges from € 2.042,- gross per month in the first year up to € 2.612,- gross per month in the fourth year. In addition to this, we offer a holiday allowance (amounts to 8%), an end-of-year bonus of one extra month, and other interesting fringe benefits.
