Deuterium Retention in Tin Depending on Temperature

Wall Forum
In order to asses the useability of liquid Sn as a plasma facing material, it is necessary to gather fundamental data on the behaviour of Sn under hydrogen isotope plasma irradiation. In this talk, results on D retention, surface morphology evolution and erosion of Sn will be presented. This talk was held at the End of Year Meeting 2019 of the EUROfusion work package DTT1-LMD.

Zeigt uns Star Trek die Energieversorgung der Zukunft?

Institutskolloquium
Wenn das Raumschiff Enterprise zu fremden Planeten reist, benötigt es dafür eine exorbitante Menge an Energie. Wie wird diese Energie erzeugt bzw. gespeichert? Wie funktionieren die Fusionsreaktoren und der Warp-Reaktor an Bord der Enterprise und wie der Impuls- und der Warp-Antrieb? Welche Visionen hatten die Star Trek-Autoren bzgl. der Energieversorgung von Kleingeräte wie Tricorder, Phaser oder dem Kommunikator? Ein Vergleich zu heutigen Technologien macht deutlich, dass wir noch weit von den Möglichkeiten der Energiespeicherung, wie sie bei Star Trek gezeigt wird, entfernt sind. [mehr]

The shape of flowing water

Institutskolloquium
  • Datum: 06.03.2020
  • Uhrzeit: 10:30 - 12:00
  • Vortragende(r): Prof. Tomas Bohr
  • Tomas Bohr is Professor at DTU-Physics. His research area is fluid dynamics, biophysics, chaos, turbulence and statistical mechanics. He combines theoretical work with simple model experiments on hydraulic jumps and other free-surface and sap-flows in trees (see http://www.fysik.dtu.dk/complex). Member of the Royal Danish Academy of Sciences and Letters and he has published around 110 papers in international journals as well as popular science papers and the book ”Bevægelsens uberegnelige skønhed. Om kaos”, Gyldendal 1992.
  • Ort: IPP Greifswald
  • Raum: HGW S1 (Übertragung Hörsaal D2)

The shape of flowing water When we observe fluid flows in nature, it is often because we notice the deformation of the fluid surface e.g., when light reflects on a water drop or an ocean wave. Such deformations can have great beauty and complexity, since the shape of the free surface is intimately and very nonlinearly coupled to the internal flow. In the talk, I will show examples of “simple” flows that, via a combination of inertia, gravity, friction, centrifugal forces and surface tension, generate surfaces with strong deformations, and that lead to interesting symmetry breaking transitions, where sharp corners and polygonal structures appear - even in strongly turbulent flows. The two basic examples are hydraulic jumps and rotating polygons illustrating these phenomena for laminar and turbulent flows, respectively, and it will be shown that, despite their large differences in Reynolds numbers and instability mechanism, they both rely on a transition between supercritical and subcritical flow. The phenomenon of “flow separation” will be shown to play a decisive role in the determination of flow structure and surface shape, and its importance will be further illustrated by examples from the formation and metamorphoses of sand-ripples. If time permits, I shall briefly discuss the recent attempt by Y. Couder and his collaborators to explain the mysteries of quantum mechanics by bouncing droplets moving and interacting through surface waves. [mehr]

Master your doctoral project successfully

HEPP Seminar
Project management in an academic environment means: putting a project into effect along-side many other activities as quickly as possible, with great complexity and with the participation of highly diverse interest groups. This challenge requires a wealth of methodological competence and interactive skills. [mehr]
