Abstract

The production of monodisperse tracer particles with suitable properties for optical flow investigations, such as small size, spherical shape, smooth surface, appropriate density and diffraction index, non-evaporating and agglomerating, electrically neutral, non-toxic and easily removable, is a challenging task. It is shown that high concentrations of narrow band particle size distributions, with a mean diameter below 1 µm, can easily be generated by means of multi-hole nozzles under overcritical pressure conditions.
