An experimental study was performed to investigate the flame-holding of hydrogen jet injected into supersonic cross-flow interacting with an incident shock wave. Pre-burned rich hydrogen or air was injected in supersonic airflow at Mach 2.5. The injection pressure was 1.2MPa or 1.6MPa. The deflection angle of the shock generator was 10 deg. Velocity profiles near the wall and those of recirculation zones around the injection slot could successfully be measured using newly-devised PTV method in this study. The velocity profiles showed that re-attachment point of separation downstream of the injection slot moves downstream when the incident shock wave is introduced to downstream of the injection slot. The re-attachment point with the incident shock wave in case of the injection pressure of 1.6MPa was not so different from that of 1.2MPa. However, extinction limit in case of the injection pressure of 1.6MPa extended than that of 1.2MPa.
