Abstract
A collaborative project funded by the Federal Ministry of Education and Research (BMBF) in the framework of the R&D program “Energie 2020+” by four Universities, two Research Centres and ANSYS is coordinated by Helmholtz-Zentrum Dresden-Rossendorf (HZDR). The project is directed towards the development and validation of CFD models of boiling processes in PWR in the range from subcooled nucleate boiling up to the critical heat flux. The work is oriented towards basic research and focused on model development, simulation and experiments on different scales. An important objective is the education and maintaining of competence in nuclear technology.
Kurzfassung
In einem Verbundprojekt im Rahmen des Programms “Energie 2020+” gefördert durch das Bundesministerium für Bildung und Forschung koordiniert durch das HZDR arbeiten 4 Universitäten, 2 Forschungszentren und ANSYS zusammen. Das Vorhaben ist auf die Entwicklung und Validierung von CFD-Modellen von unterkühltem Sieden bis zu Filmsieden gerichtet. Ein wichtiges Ziel besteht in der Ausbildung und Erhaltung der Kompetenz auf dem Gebiet der Kerntechnik.
