For our Institute of Low Carbon Industrial Processes in Zittau we are looking for a

Improved mesh generation for fixed beds for the direct reduction process of iron oxide pellets

What to expect:

With the increasing burden of atmospheric carbon dioxide on our environmental ecosystem, the decarbonisation of the steel industry is of major importance. In the view of a more sustainable steel production, the DLR Institute of Low-Carbon Industrial Processes is working on a breakthrough technology called direct reduction. In this process, iron ore pellets are reduced with a synthesis gas or even green hydrogen. Detailed CFD models of fixed beds are being developed and compared with experimental data. The aim of the Internship is to improve the mesh generation process and run detailed CFD simulations of the direct reduction.

• familiarization with OpenFOAM and with the implemented workflow:
  • run a DEM simulation to determine the pellets position in a fixed bed
  • extract the positions and generate a mesh with a third-party software
  • run the multiphase reactive CFD simulation
• tests of different meshing algorithms
• treatment of the points of contact between pellets during mesh generation
• verification of the mesh quality by running CFD simulations of the DR process
• automate the fixed bed mesh generation process

What we expect from you:

What we offer:

DLR stands for diversity, appreciation and equality for all people. We promote independent work and the individual development of our employees both personally and professionally. To this end, we offer numerous training and development opportunities. Equal opportunities are of particular importance to us, which is why we want to increase the proportion of women in science and management in particular. Applicants with severe disabilities will be given preference if they are qualified.

Further information:

Starting date: as soon as possible
Duration of contract: 3 months (or tied to the specified length of the internship)
Type of employment: Full time (part time possible)

Remuneration: in accordance with applicable DLR internship guidelines
