Research Associate (m/f/d) - Keyword: 28-2026 Energy Storage -

The Energy Storage Junior Research Group brings together young scientists working on different energy storage technologies. The aim of the position advertised here is to develop simulation methods for heat storage systems.

As part of the project, the post holder (m/f/d) will work on the following tasks in particular:

• Mathematical modeling (analytical, empirical) of flow and heat transport during charging and discharging of different sensible, latent and hybrid thermal energy storage systems,
• Performing numerical simulations, preferably with COMSOL Multiphysics, to generate intermediate results for detailed questions,
• Carrying out accompanying experimental investigations in the thermodynamics and thermal engineering laboratory for selected heat transport phenomena.

The following knowledge and skills are required

• Completed (technical) university degree in mechanical engineering or energy and environmental engineering,
• experience in the mathematical modeling of components of thermal energy systems,
• experience in planning and conducting experimental studies,
• Experience in the field of numerical simulation of flow and heat transport processes (preferably with COMSOL Multiphysics),
• Experience in the preparation of reports and presentations (R&D results).
