Researcher in Aerothermodynamic R&D Related to Heat-Exchanger Aerodynamics of Future Aircraft

Are you passionate about developing the sustainable aircraft technogies? Apply for an R&D position that focuses on the aerothermodynamic design of heat-exchanger solutions for fuel-cell powertrains.

Job description

The aviation industry stands at the forefront of its highly-needed transition to sustainable operation. To achieve this, the aviation sector focusus on research and development (R&D) of new technologies that aid towards climinate neutral aviation. Within the Netherlands, the National Growth Fund project `Aviation in Transition’ created an incubator for the development of novel technologies, with the involvement of industry, research institutes, and universities. This particular vacancy is funded through this large project (sub-project HAPSS: Hydrogen Aircraft Powertrain and Storage Systems), and is concerned with the core aerodynamics of thermal management systems.

Thermal management systems (TMS) continue to form a design bottleneck for fuel-dell driven aircraft. Enhancing heat transfer capabilities from established technologies, so that the TMS systems do not come with large aerodynamic penalties, requires further R&D and is critical for the viability of the proposed powertrain solutions. For regional aircraft, it is not uncommon for fuel-cell systems to produce in the order of 2MW of heat per engine (particularly during take-off and top-of-climb). The waste heat comprises low temperatures, which makes energy-recovery challenging. In addition, in the critical phase of maximum required cooling power, the aircraft does not operate at its cruise velocity and can still be surrounded by relatively warm atmopsheric conditions.

In ongoing activities at TUD we work on enhancing the aeothermodynamic performance of thermal management systems. In particular, our efforts are related to the heat exchanger, which can be ducted or skin-embedded, or a combination thereoff. In this context, we are looking for a highly skilled and motivated candidate who works on several aspects of heat exchanger aerodynamics:

• Low-fidelity aerodynamic models are to be developed to allow for sizing studies, for aerodynamic optimization, and for system trade-offs to-be-performed. This branch of work will contribute to feasible solutions for profitable medium-range aircraft.
• In addition, fundamental innovations are required in forced thermal convection with high Reynolds number flows, relevant to both ducted and skin-embedded heat exchanger concepts. Experimental rigs are to be developed within the Flow Physics & Technology laboratories, to investigate heat transfer performance, aerodynamic penalties, and heat transfer performance of novel surface-technologies.

(Note that you can lead the project on the TU Delft side, with ample opportunities to steer the project).

In your position, you will work closely with a young and energetic team which offers a stimulating and inclusive working environment for developing your research & academic skillset. In addition, given the multi-disciplinary nature of aerothermodynamic research, your undertakings will contribute to other projects on different themes related to non-adiabatic flows. We are looking for candidates who are interested in a position as research engineer (MSc education finished).

Requirements

We will consider applications based on the following skillsets. If you do not fullfil all requirements, please still apply (there is room for learning-on-the-job).

• A M.Sc. degree with a focus in fluid mechanics and heat transfer (e.g., aerospace engineering, mechanical engineering, or applied physics);
• An aptitude for working in a team and excellent communication skills in spoken and written English;
• Fundamental knowledge of fluid mechanics, heat transfer, and viscous fluid flows;
• Strong analytical skills; knowledge of physics, math and mechanical design is an asset;
• Strong affinity with (and background in) modelling of (non-adiabatic) fluid flows and optimization of low-fidelity models for aero-thermal systems;
• Strong affinity with (and background in) design of experiments and experimental techniques;
• Affinity with data processing techniques and programming (Matlab and/or Python);
• Hands on with lab-work, skilled in experimental design and hardware construction;
• Creativity, assertive attitude, and perseverance

The selection process will start immediately; the intended start date is in the Spring of 2025 but is subject to discussion.
