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.

Better simulations for lightning and high-voltage technology

Better simulations for lightning and high-voltage technology

Until recently, it was not clear how lightning could start. CWI PhD student Casper Rutjes modelled and simulated the origin of lightning and ionizing radiation from storm clouds and explained the physics of these phenomena. On 15 March he defended his PhD thesis. His results are important for lightning research, high-voltage technology and nuclear medicine models.

In Memoriam Willem Hundsdorfer

In Memoriam Willem Hundsdorfer

With sadness, we let you know that our colleague Prof. Willem Hundsdorfer passed away on Friday 10 November, at the age of 63. Since 1984 Willem had been affiliated with CWI; first in the Numerical Mathematics department, where he built up an international reputation. Since 2002, he had been part of the Multiscale Dynamics research group, where he shared his expertise for developing simulations of electric discharges that by now are widely recognized.
