At the division of Applied Mechanics and Energy Conversion (TME) of the Department of Mechanical Engineering at KU Leuven, the LowCarb Research group led by Asst. Prof. Joshua Lacey focuses on the decarbonization of industrial processes. This includes characterizing thermal-fluid processes that utilize alternative fuels such as hydrogen.

At the University of Melbourne, the Combustion CFD group led by Associate Professor Mohsen Talei focuses on developing predictive tools that can be used to design cleaner gas turbines and reciprocating engines. They use high-performance computing (HPC) to conduct simulations of different phenomena related to the combustion of alternative fuels such as hydrogen and biomethane, addressing both fundamental problems as well as real-world applications.

Project

Hydrogen stands out as a promising fuel in our efforts for energy decarbonization, and its use is often discussed as a method to avoid carbon emissions from reciprocating engine applications. While this option has been considered in previous studies, there are still areas to explore before the technology can be deployed in a robust manner. The notion of directly-injected (DI) hydrogen is still quite nascent, and this offers the possibility to induce charge stratification, potentially avoiding abnormal combustion events. Hydrogen flames also behave quite differently to those of other fuels, as they are able to closely approach walls before extinguishing, impacting the temperature gradient and energy flux at chamber boundaries. A comprehensive characterization of such phenomena necessitates a combined approach of coupled experiments and simulations in order to adequately resolve the interconnected chemical and hydrodynamic processes occurring in the combustion chamber. The two students selected for this project will have a unique opportunity to undertake these activities not only within two complementary research groups, but also in two different countries (Belgium and Australia). Students will spend time at both KU Leuven and the University of Melbourne within the research groups of Asst. Prof. Joshua Lacey and A/Prof. Mohsen Talei. While the students will operate independently of one another, there are common elements between the students’ topics, creating opportunities for them to share understanding and knowledge between themselves and the respective research groups at each institution. Selected students should be prepared to conduct experiments as well as detailed numerical simulation.

Profile

You have the scientific curiousity that drives doctoral students with a keen interest in green technologies such as hydrogen. You are capable of operating independently, but also within multiple research teams composed of multidisciplinary backgrounds.
The candidates:

• Hold a Master’s degree in Mechanical Engineering or the equivalent.
• Have adequate English communication skills and can present results competently and comprehensively in research team meetings, conferences and peer-reviewed journal papers.
• Are flexible and have good time management skills.
• Can work autonomously and maintain good interactions with the co/supervisors.
• Have the necessary skills to successfully conduct cutting edge experiments, process measurements and undertake detailed computational fluid dynamics simulations.
• Help in the organization of workshops and other events.
• Frequently report the progress of the conducted research to the co/supervisors.
• Are willing to engage in teaching assignments.
• Are willing to travel between Belgium and Australia for this unique PhD undertaking.

Offer

• A unique opportunity to work within two research groups at KU Leuven and the University of Melbourne.
• Become a part of top-ranking universities within multidisciplinary teams.
• The opportunity to pursue a joint PhD degree that is fully supported for 4 years, including travel between Belgium and Australia.
