Picosecond vortex dynamics in magnetic nanostructures: the interaction between vortices and spinwaves Ghent University
Being the simplest non-trivial configurations of magnetic nanostructures, vortices are not only interesting study objects, but offer new perspectives for magnetic data storage. An optimally pulsed synchrotron X-ray source will be used to investigate the ultra fast dynamics of the vortex core in an X-ray microscope. Additionally, the interaction of spin waves with the core dynamics will be investigated.
Picosecond vortex dynamics in magnetic nanostructures: the interaction of vortices with spinwaves. Ghent University
In this project, we will address the interaction of spin waves with vortices and domain walls. These have their own dynamics, and understanding how spin waves can interact can lead to new functional magnetic devices. Magnetic resonance spectroscopy, time-resolved X-ray microscopy and advanced simulation tools will be deployed to study these interactions in nanometer sized wires and platelets.

Numerical simulation of expanding swirling flows with a hybrid RANS/LES turbulence model Ghent University
Vortex precession and vortex breakdown in swirling abruptly expanding jets are simulated with a hybrid RANS-LES turbulence model. In the core of the flow, coarse grid LES is used with an e-model as subgrid model (1 dynamic euation). In wall vicinity, the same model is used as RANS model with a mixed low Reynolds number and wall function description.
