Hydraulic divider geometry optimization with the use of CFD analysis tools
Since 2012, National Centre for Nuclear Research in Poland is constructing its own Data Centre for HPC under the name Świerk Computing Centre (CIŚ). It will be ready in 2015 reaching its target - 500 TFLOPS. One of its major current problems is the unstable work of HPC cluster cooling system, resulting in the increase of the maintenance costs. The main aim of this work is to investigate this problem with use of the Computational Fluid Dynamics (CFD) code. The investigation is focused on the system part called fluid divider that is suspected to be a source of unstable system operation. In this paper, wide range of cases will be analysed, covering different work regimes of the installation and various geometry modifications. Finally, certain improvement in the current design will be suggested by the CFD Analysis Group.
