Centrum Wiskunde & Informatica (CWI, the Dutch national research institute for mathematics and computer science) has a vacancy in the research group on Multiscale Dynamics for
a Postdoc (m/f/x) to develop computational models for electric breakdown of gases
Job description
Electric gas discharges occur in nature, most prominently in air in the form of lightning and its less visible precursors. Similar gas discharges occur in high-voltage equipment, such as the switchgear used in electric grids. Our transition to sustainable electric energy requires major extensions of this grid. However, switchgear and other high-voltage equipment currently often operate with SF6 gas, which is the worst greenhouse gas known. Within the project, we investigate electric discharges in “green” alternatives to SF6. For further information, see https://homepages.cwi.nl/~ebert/2023-ERCIM-News.pdf
We are seeking a postdoc to develop computational models of electrical breakdown of gases. Breakdown occurs in several stages: streamer discharges form, some of them can turn into leaders due to gas heating, eventually resulting in a spark. Simulating all these stages in detail is computationally unfeasible, so the goal is to develop a simplified model focusing on the leader stage. You will:
- Analyze experimental data and microscopic simulations
- Identify relevant physical features and parameters
- Apply machine learning techniques to build predictive models
- Collaborate closely with experimentalists and modelling experts
Project Environment
This position is part of a collaborative research project involving:
- Two PhD students at TU Eindhoven, conducting experiments
- A PhD student at CWI, focused on modelling streamer discharges
- A committee of industrial users, ranging from start-ups to multinationals, providing feedback several times per year
Our modelling group at CWI Amsterdam has extensive expertise in modelling the dynamics of gas discharges. We have developed several microscopic models for the early stages of electric discharges as well as analytical approximations to grasp their multiple spatial and temporal scales. Experimental partners at TU Eindhoven include the group of Sander Nijdam, an expert in measuring streamer discharges with highest resolution, and the group of Tom Huiskamp, who focusses on new solid state high voltage sources and their applications.
Requirements
- Previous experience with electric discharges, either experimental or computational
- Affinity for computer simulations
- A finished PhD thesis (at least submitted to the PhD committee by the time you start)
Terms and conditions
The appointment will be for 20 months (based on a fulltime position, but longer with a part time position) and the gross monthly salary for an employee on a full time basis, depending on relevant work experience, ranges from € 4.501 to € 5.486. Specifically, the terms of employment are in accordance with the Dutch Collective Labour Agreement for Research Centres ("CAO-onderzoeksinstellingen").
Employees at CWI/NWO-I 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.
