Paper Abstract

Application of particle image velocimetry (PIV) to a scale transonic wind tunnel and to a cold burner spray is described. It is shown that diffraction limited imaging makes it possible to extend the working range of PIV systems to several meters enabling a broad variety of industrial applications and to determine particle sizes with a high magnification objective. In both cases diffraction limited imaging significantly reduced the laser energy required to form satisfactory particle images. Particle images were recorded onto 35 mm film and a CCD video camera.
