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
Numerical results were compared with the 4-stage rig test results.
