Description
Leader of the group Multiscale Dynamics: Ute Ebert.
Nature and technology are full of dynamics, often involving multiple scales in length, time and energy. To model these processes, we combine scientific computing with model reduction and machine learning, with particular focus on plasma dynamics in lightning and space weather, and in high voltage and plasma technology.
Our research addresses questions in nature such as start and propagation of lightning strokes, terrestrial gamma-ray flashes and space weather, and closely related technological problems such as switch gear for long-distance electricity nets, air purification and disinfection with corona reactors, and protection of satellites and electricity nets from space weather.
Within national and European projects, we collaborate with colleagues in applied plasma physics, electrical and mechanical engineering, atmospheric electricity, and cosmic particle and space science, and with non-academic partners such as ABB, DNV-GL, ESA-ESTEC and NASA.

Vacancies
PhD Student on Computational Modelling of Lightning
You will have the opportunity to advance our understanding of lightning dynamics through physical modelling and computational science. Central questions for the PhD projects include: When and how do electric discharges grow until they finally form the visible lightning channel? Why do negative discharges propagate in steps and positive ones continuously? How much can electrons be accelerated at the tips of growing lightning channels, and can this mechanism explain terrestrial gamma-ray flashes emitted by thunderstorms?

News
Vidi grant for Enrico Camporeale’s space weather research
CWI researcher Enrico Camporeale received a Vidi grant from NWO for his proposal 'Real-time forecasting of killer electrons on satellite orbits' in May 2017. He received the 800,000 euro grant to develop his own innovative line of research and to set up his own research group within five years. Camporeale will develop a technology to forecast space weather events that could harm satellites, power networks and communication systems. This forecast would allow to take countermeasures.
New electricity grids possible with computer simulations
Renewable energy requires new electricity grids, sometimes over entire continents, because 'green energy' is often generated in remote locations.
Four million euro for EU SAINT network on thunderstorm research
In May 2016 the EU 'SAINT' Innovative Training Network in the Marie Skłodowska-Curie Actions Programme was awarded a 4 Million euro grant. SAINT stands for ‘Science and Innovation with Thunderstorms’. Its 19 partners come from both academia and non-academia, such as NASA, PLASMAT and Airbus.
Cum laude for 3D modelling of pulsed discharges in air
PhD student Jannis Teunissen from Centrum Wiskunde & Informatica (CWI) has made major progress in modelling the early stages of electric discharges as they occur in lightning, high voltage electricity nets and plasma technology. He received a 'cum laude' predicate for his thesis '3D Simulations and Analysis of Pulsed Discharges', which he defended on 12 November 2015 at Eindhoven University of Technology.
