Workflow / Objective:
Even in 2016, Germany's total primary energy consumption was covered only by 3.9 % from photovoltaic, hydro and wind power and but still more than 80% from fossil fuels. In light of this, the development of nuclear fusion reactors is a useful supplement to other solution strategies for the growing energy problem.
The first wall of future fusion reactors (DEMO) is subject to high thermal loads (up to 1 MW/m2). With numerical flow simulation techniques accurate heat transfer for the cooling channels of the first wall can be calculated. The cooling channels are rectangular, one-sided ribbed and helium perfused channels. The aim is to keep the temperature in the wall material below 500 °C. Different rib configurations should to be investigated with regard to their effects on the heat transfer.
The work includes:
- Training in numerical fluid mechanics, turbulent flows, heat transfer
- Meshing with Ansys ICEM CFD running the simulations with Ansys Fluent
- Detailed evaluation of results (postprocessing) and interpretation of the results
- Written elaboration of the procedure and the results
