Wave heating and turbulence in the solar atmosphere

Date: 01.12.2017
  • Promotor(s): Norbert Magyar
  • Institution(s): KU Leuven
  • Domain(s): Astronomy and astrophysics
The Sun is one of our most important plasma “laboratories”, where theories of plasma dynamics can be tested through observations. Despite its proximity in astronomical scales, allowing for detailed observations, the solar atmosphere is still enigmatic, harbouring one of the last unsolved problems of classical physics, the coronal heating problem. Via high-resolution magnetohydrodynamic (MHD) simulations, we aim to determine and quantify the dissipation and heating by MHD waves through turbulence or resonant absorption, in different plasma geometries found in the solar atmosphere.

Study of magnetic cusp properties with Particle In Cell simulations

Date: 01.12.2017
  • Promotor(s): Diego Gonzalez Herrero
  • Institution(s): KU Leuven
  • Domain(s): Astronomy and astrophysics
A magnetic cusp is a plasma trap in the shape of a cone which is present in the magnetic fields above and below the poles of the Earth. It is also used for plasma confinement in fusion reactors. In Fusion, magnetic cusps are used because, contrary to others confinement schemes (like tokamac or stellerator), inside the magnetic cusp the plasma always face convex magnetic lines, making It more stable. Using the Particle In Cell code ECsim we will study the beahviour of the magnetic cusp with different plasma parameters and system configurations. The results of this work will give us an insight on the physics of the magnetospheric cusp and will help to improve our understanding of plasma confinement.

Formation and eruption of solar prominences

Date: 01.12.2017
  • Promotor(s): Chun Xia
  • Institution(s): KU Leuven
  • Domain(s): Astronomy and astrophysics
With 3D magnetohydrodynamic simulations, we hope to numerically reproduce the formation and the eruption of solar prominences, considering both the magnetic flux rope structures and the thermodynamic plasma. The detailed magnetic reconnection processes for the flux rope formation in chromosphere and solar flares, triggered by the erupting prominences, in corona will be studied with 3D modeling.

Anual energy production (AEP) estimates of Cabauw and Fino1 based on large-eddy simulations

Date: 01.12.2017
  • Promotor(s): Johan Meyers
  • Institution(s): KU Leuven
  • Domain(s): Technology
The New European Wind Atlas (NEWA) project aims to improve wind resource assessment at new or existing wind farm sites. In this context, the objective of the NEWA Meso-Micro Challenge is to test coupling methodologies for various sites and map accuracy versus cost for relevant quantities of interest, notably for annual energy production (AEP). The current project will perform large-eddy simulations to provide an AEP estimate and an accuracy versus cost figure at the high-fidelity end of the model range based on two different coupling strategies for both onshore and offshore locations. The computational challenge lies in the wide variety of flow regimes and the extensive time horizons required for AEP estimates.

Optimal dynamic induction and yaw control of wind farms in the atmospheric boundary layer

Date: 01.12.2017
  • Promotor(s): Johan Meyers
  • Institution(s): KU Leuven
  • Domain(s): Technology
In wind farms, complex aerodynamic interactions between neighboring turbines, as well as an interplay between the farm and the atmospheric boundary layer (ABL) play an important role in overall wind-farm performance. Current control strategies optimize individual performance at the turbine level and do not account for these interactions, resulting in sub-optimal farm efficiencies. Here, we aim to increase total wind-farm power output by controlling the turbines in a coordinated manner through deviations from locally optimal induction and yaw settings. The combination of large-eddy simulations with adjoint-based optimization allows to optimize the farm as a whole, accounting for all relevant interactions with the ABL.
