ABSTRACT:
Microscopic, neutrally buoyant particles containing fluorescing compounds used for tracers of large scale turbulent flows. The particles are generated by dissolving acrylics in a solvent and mixing the solution with fluorescing dyes. This mixture is sprayed into a heated chamber where the solvent evaporates, and the solid acrylic with the imbedded dye settles on the bottom of the chamber. The dust is collected, and the particles are separated according to size using a filter. Dye residue on the particles' surface is washed leaving the dye imbedded within the particles. The particles are then used within flow fields.
