The Institute of Engineering Thermodynamics (ITT) at Hamburg University of Technology is a fast-growing research institute focusing on experimental and simulation-based research on complex energy systems. We are seeking a highly motivated PhD candidate to work on second-law-based analysis and design of packed-bed thermal energy storage systems. The research is funded by the German Research Foundation (DFG) within the Priority Programme “Carnot Batteries: Inverse Design from Markets to Molecules” (SPP 2403).

The successful candidate will use system-level simulation (Modelica) and computational fluid dynamics (CFD, OpenFOAM) to investigate the charge and discharge processes in packed-bed thermal storage systems. Based on the simulation results, a second-law analysis will be performed, and an inverse design model will be developed to identify suitable material combinations and system configurations.

The position offers the opportunity to work in a dynamic research environment and collaborate with leading research institutes in Germany through the DFG SPP program. The project is a perfect opportunity to contribute to the ongoing energy transition and TU Hamburg's mission "engineering to face climate change".

YOUR TASKS

• Simulations of the transient charge/discharge processes of packed bed storage systems


• Second-law-analysis of the simulation results to understand the loss mechanisms


• Development of an inverse design model


• Publishing research in peer-reviewed journals and present results at international conferences


• Contribute to the Institute beyond the dedicated project work

YOUR PROFILE

Requirements

• Completed scientific university studies (masters degree or equivalent), in particular in the subject mechanical engineering, process engineering or other relevant disciplines

Desired knowledge and personal skills

• Expertise in thermodynamics, heat transfer, and fluid mechanics


• Good experiences in system simulation or (and) CFD simulation


• Solid knowledge in energy systems


• Excellent communication skills in English and (or) German


• The ability to work independently within an interdisciplinary research team

OUR OFFER

• A job in an interesting, friendly and appreciative working environment


• Intensive induction/ onboarding


• Flexible and family-friendly working conditions


• Possibility of mobile working


• 30 day vacation per year
