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 and high energy-density of hydrocarbon fuels. However, these fuels will change more and more from fossil originated to sustainable ones, like biofuels and solar fuels. Natural gas fired central heating boiliers will also undergo this transition as it is expected that biogas and hydrogen will be mixed more and more into the natural gas supply system.
This project deals with central heating systems equipped with burners made from fibre materials, a promising and relatively new kind of burner design. The ultimate goal of the project is to elaborate a methodology for the optimal design of this kind of burners aiming clean, robust, and thermo-acoustically stable operation in different apliances. The approach is to apply existing knowledge of laminar burners to perforated fibre mats and to study which geometry leads to best achievable performance in terms of operation range, emissions but also in terms of thermo-acoustic stability.
The PhD student will study the performance of perforated fibre mat burners experimentally and numerically. A standard setup will be developed to study combustion behavior, (thermo-acoustic) stability and emissions by operating with natural gas including hydrogen addition. Detailed numerical simulations of the flames, their emissions as well as their flame-acoustic interactions will be performed as well. The current group has vast experience in experimental and numerical studies of such flames and the existing knowledge and equipment will be applied to this. Thermo-acoustic studies of such burners inside heating boilers will be performed as well. This will lead to new insights into optimal application of perforated fibre mat burners in central heating systems.
Qualification of applicants
We are looking for a recently graduated, talented, enthusiastic candidate with excellent experimental, numerical and communication skills, holding an MSc in Mechanical Engineering, Aerospace Engineering, Applied Physics or equivalent, with a solid background in thermo- and fluid dynamics. It is the intention that the research will lead to a PhD degree.
The Power & Flow section within Mechanical Engineering focuses on clean and efficient combustion and process technology, to cater for fast-growing energy demands. We are also seeing increased use of biofuels, and eventually the emergence of fuels derived from sustainable sources, such as solar and hydrogen. Optimizing combustion and process devices, in combination with different fuel formulations to minimize undesired emissions and maximize thermal efficiency, is essential to supporting both of these developments.
The group has a unique research infrastructure, both from an experimental and computational perspective. The group has a world-wide reputation on experimental and numerical tackling of combustion problems (in particular the Heat Flux Method and the Flamelet Generated Manifolds technique).
