Combustion is responsible for 80% of our current energy supply, and will remain to be extremely important in the foreseeable future due to the high power-density of hydrocarbon fuels. However, these fuels will change more and more from fossil fuels to sustainable fuels, like biofuels and solar fuels. And to the non-carbonaceous metal fuels. To contribute to the energy transition by developing an understanding of the underlying physical and chemical processes in the combustion of this new generation of fuels, and to control them in such a way that the processes are ultra-clean and highly efficient, is highly motivating.

One of the newly concieved ways to convert energy involves rethinking the way we use metals. People deal with metals every day, yet it may be hard to imagine that metals can replace hydrocarbon fuels. Nevertheless, recent research has indicated that there are huge opportunities for a carbon-free, sustainable energy cycle based on metal fuels, that can supply power and heat when and where needed. In order to make fast oxidation of metals possible, the metal fuel should be used as small (micron-sized) particles. In that case, they can generate flame structures similar to those of gaseous fuels. Many of the details and practical issues of burning metal fuels are, however, still unknown.

Thanks to a large grant supported by the European Research Council, TU/e is searching for 3 experiment-oriented PhD students in the field of metal combustion. You will work together, and with colleagues developing numerical models of metal flames, to set up a sound fundamental basis for understanding such flames from first principles. This new multi-scale framework for the modelling of metal fuels  is to be supported by a wide variety of (laser-diagnostic) measurement techniques. The project consists of 3 parts (the columns in the accompanying, schematical figure), each with an experimental and a numerical component (the rows in the figure):

1. The influence of environment and inter-particle interactions on the combustion of single particles (left);
2. The creation and propagation of flame fronts dominated by mutual ignition (middle);
3. The creation of 3D metal aerosol flames by superposition of multiple flame fronts (right).

Qualification of applicants

We are looking for 3 recently graduated, talented, enthusiastic candidates with excellent experimental and communication skills, holding an MSc in Mechanical Engineering, Aerospace Engineering, Applied Physics or equivalent, with a solid background in thermo- and fluid dynamics. A strong interest in energy conversion methods in the energy transition is required. The experimental work will focus on laboratory-scale metal powder flames, dedicated for detailed studies of combustion characteristics using a variety of mainly optical diagnostics. Thus, experience in laser-based, optical diagnostics is a benefit. It is the intention that every position will lead to a PhD degree.

We offer:

• An exciting job in a dynamic work environment and multidisciplinary consortium.
• A temporary position of 4 years.
• Depending on knowledge and experience, the gross monthly salary amounts to a minimum of € 2,395 and a maximum of € 3061. This is in accordance with the Collective Labour Agreement for Dutch Universities.
• The possibility to present your work at international conferences.
• An attractive package of fringe benefits, including end-of-year bonus (8,3% in December), an extra holiday allowance (8% in May), moving expenses and excellent sports facilities.
