Outline of Final Research Achievements

The measurement of the shock wave in the narrow channel is hardly performed because of the representative scale difference between the flow and the sensors.
The aim of this study is to experimentally clarify the characteristics of the shock wave propagating in the narrow channel by generating the shock wave in the rectangular tube. As the first step of this study, the opening time of an improved main piston, which has the separated structure, is reduced about 85% compared with the conventional main piston. As the second step, the cross section of the shock tube is changed from circle to rectangular. Additionally, the measurement of the shock wave propagating in the narrow channel with rectangular cross section can be performed by using newly constructed several interferometers.
