Reasons and benefits of using JAXA Supercomputer System

The unsteady analyses 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

A full circumference unsteady analysis was performed to simulate rotating stall in the compressor cascade and investigate its mechanism.
