A variable cross-section shock tube and a reflected shock tube are applied to the facility. As the characteristics of the powder injector, the pressure measurement and the optical visualizations were carried out. The pressure measurements were conducted in the driven section and at the nozzle exit for the flow characteristics. In addition, the flight velocity of the powder particles with the order of 10 μm was measured by particle tracking velocimetry (PTV) method using ultra high-speed video camera with high spatial and temporal resolution. Moreover, the visualization inside the driven section was carried out to investigate the detailed behavior of the powder particles.英語フィールド
