摘要：

Molecular tagging velocimetry using air photolysis and recombination tracking (APART) was applied to the wake flow of a 30degrees wedge in a small Mach 3 wind tunnel. Average velocities could be determined with a standard deviation down to 0.4% (free stream) and 7% (expansion fan behind wedge). Instantaneous velocities (measurement time 7 mus) could be recorded with a standard deviation down to 2%, limited by the available laser power. The measured velocity profile behind the wedge is compared to a simulation.
