Velocity measurements have been made in a large-scale transonic wind tunnel using particle image velocimetry. Diffraction-limited optics have been used to image seeding particles at up to 2.5 m from the flow. A practical system to record the data has been constructed such that the camera can be remotely focused on the plane of interest. Particle images were recorded onto 35 mm film. Results were obtained from Mach numbers 0.2 to 0.8, and automatically analysed to produced vector maps of the planar velocity field. It has also been shown that particle image velocimetry data can be successfully recorded onto a charged coupled device image sensor at transonic speeds. This approach eliminates the need for photographic processing and allows real time data acquisition in a digital form. The potential is then apparent for automatic, and near real-time processing, of particle image velocimetry data.
