Type of employment


"Cutting-edge research requires excellent minds – particularly more females – at all levels. Launch your mission with us and send in your application now!" Prof. Pascale Ehrenfreund - Chair of the DLR Executive Board

Your mission:

The Solar Tower Systems Group of DLR’s Institute of Solar Research has been doing extensive research on Central Receivers to develop cost-effective and commercializable technologies. Thanks to its high heat storage capabilities and durability at elevated temperatures, particle based solar receivers draw attention of many research groups. DLR’s Institute of Solar Research has designed, patented and developed the Centrifugal Solar Receiver (CentRec®), which has experimentally proven capability to provide 965 °C of particle outlet temperature with a 2.5 MWth-prototype (www.dlr.de/centrec).

The focus of this work is to further develop the available experimental test set-up and to conduct experiments with the particle based centrifugal solar receiver. In the CentRec® receiver, the ceramic particles with various diameters (0.3 mm – 1 mm) are moving in an inclined rotating drum, and exposed to concentrated solar radiation. Extensive experimental test campaigns have highlighted improvement potential in the two areas of particle feeding into the receiver and collection of hot particles from the receiver.

The main objective of this study to explore improvements and / or new designs for the particle feeding and collection. Some ideas to this end exist within in the team and development of new solutions is encouraged. An experimental test setup is available to be modified to test and validate concepts. In the development of concepts discrete element models (DEM) can be used (based on existing experience) or own models developed.

Your tasks:

  • literature review of particle-based solar receiver systems and their experimental test set-ups
  • adapt or create a DEM-model of the particle receiver
  • conceptual design of solutions for particle feeding and collection system
  • conducting experiments to investigate performance of proposed designs
  • Your qualifications:

  • studies of mechanical engineering or similar
  • hands-on experience in basic manufacturing processes like assembling etc. and practical skills for testing
  • creativity and ability to do brain storming
  • ability to work independently
  • interest in Concentrating Solar Power Systems
  • Your benefits:

    Look forward to a fulfilling job with an employer who appreciates your commitment and supports your personal and professional development. Our unique infrastructure offers you a working environment in which you have unparalled scope to develop your creative ideas and accomplish your professional objectives. Our human resources policy places great value on a healthy family and work-life-balance as well as equal opportunities for persons of all genders (m/f/non-binary). Individuals with disabilities will be given preferential consideration in the event their qualifications are equivalent to those of other candidates.
