The primary objective of the NWO-sponsored AQUA program is to gain a better understanding of the effect of water quality on multiphase flow dynamics, in particular on cavitation and air lubrication for drag reduction. The participating universities and research institutes include Delft University of Technology, University of Twente (Physics of Fluids group), and Royal Netherlands Institute for Sea Research. At Delft University, we currently have 3 open PhD positions related to this program.
Air bubbles in water attenuate underwater sound and can reduce the friction drag of a ship, as a result of which less fuel is needed. Although the behavior of air bubbles in freshwater is known reasonably well, bubbles in saline seawater behave very differently. In this program, the researchers will compare air bubbles in different types of water, varying from freshwater to natural seawater, to gain a better understanding of how bubbles can be used to manage friction, sound propagation and cavitation. The ultimate aim is to be able to predict how the water quality (gas and chemical content) influences drag reduction and cavitation hindrance.
The advertised positions concern the following research topics: (1) Dynamics of transitional air layers, (2) Water quality effects on cavitation and noise, (3) Cavitation inception in tip vortices. All projects are experimental in nature and will make use of a new, unique Multiphase Flow facility that is currently under construction. Furthermore, strong collaboration is expected, e.g. by co-developing state-of-the-art flow measurement techniques. The required infrastructure (high-speed imaging, tomographic particle image velocimetry) is available. The total duration of each PhD project is 4 years, with a target starting date of September 1st, 2019.
We are looking for 3 enthusiastic researchers, who want to develop their know-how and experience in a challenging academic environment. In more specific terms:
- The successful applicants are in the first 4 years after graduation (MSc) of their research career.
- A degree in Mechanical Engineering, Maritime Technology, (Applied) Physics, Aeronautics, or equivalent degree with a clear focus on fluid mechanics is a prerequisite.
- Experience in conducting experimental work is regarded as a strength.
- A critical and inquisitive attitude with regard to results is expected, which translates into formulating new research questions.
- Ability to function both in a team and independently.
- Good communication skills, with a sound knowledge of the English language, and both oral and written proficiency.
