Reasons and benefits of using JAXA Supercomputer System
To analyze the detailed flow field around turbo machnes, it is necessary to confirm the prediction accuracy of the analysis by DES. For this purpose, a large-scale analysis will be performed in various flow conditions, so it cannot be performed without JSS2.
Achievements of the Year
We analyzed the flow field around the centrifugal compressor with DES and confirmed that there was no problem with parallelization performance of UPACS.
