The latest developments in hardware and software for laser-based flow diagnostics enable the investigation of complex flow phenomena under enclosed, high-temperature and even pressurized conditions. However, the successful application of a velocimetry technique strongly depends on the presence of appropriate light-scattering tracer particles (seeding) in the flow. In this study, the design and development of a Seeding Generator is effectively carried out with perfect measurements considering the flow characteristics. Compressed air testing was done based on the laser sheet visualization and the flow field was visualized. The results show that the fabricated seeding generator will be able to supply seeding particles for flows from subsonic to supersonic regimes.
