PhD MODEL CALIBRATION AND RESOURCE ASSESSEMENT

1 - Working at the VUB

For more than 50 years, the Vrije Universiteit Brussel has stood for freedom, equality and solidarity, and this is very much alive on our campuses among students and staff alike. 

At the VUB, you will find a diverse collection of personalities: innovators pur sang, but above all people who are 100% their authentic selves. With some 4,000 employees, we are the largest Dutch-speaking employer, in the private sector, in Brussels; an international city with which we are only too happy to connect and where (around) our 4 campuses are located. 

Add to this our principle of free research - in which self-reflection, a critical attitude and an open, creative mind around scientific and social issues are central - and you have a university that is fundamentally groundbreaking and pioneering in education and research. In short: the VUB all over again. 

Moreover, the VUB is a member of EUTOPIA, an alliance of like-minded European universities, all ready to reinvent themselves.

2 - Position description

The Faculty of Engineering, Department Industriële ingenieurswetenschappen, is looking for a PhD-student with a doctoral grant. 

More concretely your work package, for the preparation of a doctorate, contains: 

The VUB Acoustics and Vibrations Research group has a core focus on wind energy as a member of OWI-lab. Our vision is to bring methodological advancements all the way to application in industry. This is achieved by working closely together with the different wind farm operators within the Belgian offshore zone: e.g. Parkwind, Norther, Otary. The main focus of the department is on performance monitoring and health monitoring of the different machine components. To this end, multiple dedicated measurement campaigns have been performed throughout the Belgian offshore zone.

   
Project detail

The European Green Deal aims to reduce emissions by 55% in 2030 compared to 1990. To this end, a target is set to have an installed capacity of offshore wind of least 60 GW in 2030. The effects of climate change on the wind resource, and consequently wind farm yield is nevertheless currently not properly understood. Initial future climate projections point to a slight decrease in wind globally and also during summertime in the northern mid-latitudes, including the North Sea. For example, preliminary studies estimated a 30-year energy production decrease of 5% in summer and 2.5% in autumn. This introduces uncertainty on the energy yield modeled during the design of the wind farm, increasing the risk for wind farm operators. To reduce this, additional insights are needed.

In this PhD, the main focus will therefore be on investigating:

(a) the calibration of engineering wake models using field measurements (LiDAR, scada)

(b) the effect of changing inflow conditions on wind farm yield

(c) the effect of precipitation on blade erosion

You will work on the ACCEMO project in collaboration with KU Leuven, who will deliver insights on the effect of climate change on meteorological conditions at various locations (North sea, southeastern Australia). The research will be further facilitated using current measurements available at VUB in the Belgian offshore zone. For example, multiple years of scada data is available to calibrate the wake models to ensure the modelled behavior matches with field observations. Multiple dedicated measurements using nacelle and scanning LiDARs have also been performed. Moreover, long-term disdrometer measurements are available to have insights in the droplet size distribution, which can be used to predict the degradation of the blade coating.

For this function, our Brussels Humanities, Sciences & Engineering Campus (Elsene) will serve as your home base. 

3 - Profile

What do we expect from you?

• You have a Master degree in Mechanical, Electrical, Mathematical engineering, or Fluid Dynamics
• Experience with or eagerness to learn in one or more of the following will also be an advantage: Pywake, FLORIS, LiDAR, wind turbine scada...
• Background in programming (Python)
• Proficiency in English
• Being willing to do (offshore) experimental work is a plus

• You have not performed any works in the execution of a mandate as an assistant, paid from operating resources, over a total (cumulated) period of more than 12 months.

• As a (non-)EEA national, meet the conditions for obtaining a valid permit for VUB and comply with the VUB residence requirements. More info here.

The VUB wants to be a reflection of the society where everyone's talent is valued, regardless of gender, age, religion, skin color, migration background, disability and neurodiversity.

4 - Offer

Are you going to be our new colleague?
