Abstract

A laser-induced fluorescence technique to diagnose a three-dimensional transonic flow with complicated shock wave-boundary layer interaction is presented. The diagnostic system consists of an argonion laser sheet traversing laterally in the flow field with seeded iodine as fluorescence material, a CCD camera with an image intensifier and a microcomputer for image processing. The temperature distributions in a rectangular duct with a swept-back bump are investigated by this system, and the structure of the flow field is clarified including the curved shock waves and the boundary-layer separation.
