Abstract
For fundamental study on propagation of detonation waves inside rotating detonatio engines, fundamental numerical analysis using CHARIOT was done. In FY2022, 2D numerical analysis on propagation of detonation waves inside a rotating detonation engine with C2H4/O2 and H2/AIR mixture gases have been calucurated.

Reasons and benefits of using JAXA Supercomputer System
Even for fundamental numerical analysisi on propagation of detonation waves, huge computational resources and high-performance CPU must be needed due to high-speed propagation and numerous erementaly reactions. JAXA’s JSS3 has enough capability to carry out numerical analysis for detonation research. Therefore, our reserach need to perform the analysis with JSS3.
