Reasons and benefits of using JAXA Supercomputer System

In this reseach, the supercomputer system is not utilized.

Achievements of the Year

(In this reseach, the supercomputer system is not utilized.)

The modeling of rotating bearing elements which is complicated because of maltiple rotating axises and rotational speeds was conducted. Using the model, the bearing heat generation induced by the fluid viscous heating was calculated.
