To investigate the transonic three-dimensional flow-field with complicated shock wave-boundary layer interaction, the laser-induced fluorescence (LIF) method was developed. This diagnostic system was based on the argon laser with seeded iodine as fluorescence material, and was applied to the rectangular duct with a swept-back bump. The temperature distributions in the duct were obtained, and the structure of the flow including the curved shock wave and the boundary-layer separation was clarified.
