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.

CWI researchers simulate how ‘coherent structures’ affect solar wind heating

CWI researchers simulate how ‘coherent structures’ affect solar wind heating

CWI researchers have further developed our understanding of how solar wind particles get accelerated and heated. In particular, they discovered how ‘coherent structures’ in the solar wind, places where the magnetic fields and electrical currents are enhanced, affect the energy transfer responsible for heating. The results were published in Physical Review Letters on 19 March 2018.

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.
