Reasons and benefits of using JAXA Supercomputer System
The number of cases of aerodynamic performance prediction of a multi-stage compressor will be very large for satisfactory results. So we can not be calculated in a realistic time using anything other than JSS.
Achievements of the Year
Various turbulence models were used to analyze four-stage rig test specimens, and the differences in aerodynamic performance and stall point prediction were clarified.
