In the context of an intensive cooperation between research groups in the Netherlands (CWI Amsterdam, Shell in Amsterdam) and in India (IISc Bangalore, Shell Bangalore), we are hiring a PhD student for research on digital twins to understand flow in pipelines. This work is based on advanced deep learning, detailed computational fluid dynamics, and the incorporation of sensor data in flow solvers.

Research work:

This project deals with the development of a digital twin for the detection of leakages in pipelines. We deal with single phase flow in water networks in the city of Bangalore and we will work on multiphase flow in industrial pipelines in collaboration with Shell as the industrial partner in this project. The digital twin connects sensor data and advanced fluid solvers in order to detect possible leakage of fluid from the

pipeline in real-time. A serious challenge within the concept of the digital twin is that the fluid flow model is typically much too slow to compute within real-time. With the help of deep neural networks (DNNs) and Generative Adversarial Networks (GANs) we aim to augment expensive fluid flow solvers by a learned function form which is much cheaper to evaluate.

Collaborators:

• Sander Bohte (CWI) is also professor at the University of Amsterdam and the Rijksuniversiteit Groningen, with expertise on neural networks and their various applications.
• Cornelis Oosterlee (CWI) is also professor at the Delft University of Technology in Applied Mathematics with experience in computational fluid dynamics, uncertainty quantification.
• Ruud Henkes (Shell) is also professor in mechanical engineering at the DelftUniversity of Technology, with expertise in fluids and particularly in pipe flow.
• Svetlana Dubinkina (CWI) is a member of the consortium with expertise in data assimilation.
• Benjamin Sanderse (CWI) is member of the consortium with expertise incomputational fluid dynamics.

There is an extensive collaboration with researchers in India and it is expected that during the research period the collaborators in India are visited several times.

The preferred excellent candidate has a Master’s degree with a solid background in computational fluid dynamics, and experience in, or high interest in, neural networks and machine learning algorithms. Preferable qualifications for candidates include proven research talent, an excellent command of English, and good academic writing and presentation skills.

The terms of employment are in accordance with the Dutch Collective Labour Agreement for Research Centres ("CAO-onderzoeksinstellingen"). The initial labour agreement will be for a period of 18 months. After a positive evaluation, the agreement will be extended by 30 months. The gross monthly salary, for a PhD student on a full time basis, is €2,346 during the first year and increases to €3,007 over the four year period.

Employees are also entitled to a holiday allowance of 8% of the gross annual salary and a year-end bonus of 8.33%. CWI offers attractive working conditions, including flexible scheduling and help with housing for expat employees.
