| Outline of Final Research Achievements |
Theoretical and numerical study of waves in real gases was carried out. Main results are summarized as follows: (1) Ultrasonic sounds and shock waves in rarefied polyatomic gases were analyzed based on extended thermodynamics (ET). The highly-nonequilibrium phenomena beyond the validity range of previous theories were successfully explained. (2) The new approach to the shock wave structure was proposed on the basis of the ET theory. This approach enables us to analyze the shock wave structure in rarefied polyatomic gases in a unified way. (3) The ET theory itself was also studied and developed.
