"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

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 areas of dosing the particle flow as well as accurate measurement of the particle flow.

In the past the team has developed and operated several solutions to measure and regulate particle mass flow. The main objective of this study is to explore improvements of the existing solutions. The innovation of new solutions is encouraged and supported. An experimental test setup is available to be modified to test and validate concepts.

Your tasks:

  • Literature review of solutions to regulate and measure particle (and granular) flow
  • Selection process of suitable solutions
  • Design, manufacturing and assembly of lab scale devices
  • Experimental campaign to confirm performance

Your qualifications:

  • Studies of mechanical engineering or similar
  • Hands-on experience in basic manufacturing processes like assembling etc. and practical skills for testing
  • CAD
  • 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.
