Droplet sizing calibration of the Phase Droppler Particle Analyzer

O'Hern, T.J.; Rader, D.J.; Ceman, D.L.

The Phase Doppler Particle Analyzer (PDPA) is an LDV-based instrument for simultaneous measurement of single particle size and velocity. A PDPA calibration was performed using well-characterized liquid droplets in the 4 to 80 μm diameter range. Two test liquids were used: oleic acid and kerosone. A standard PDPA instrument and a fiber-optic probe PDPA system were tested. The standard instrument measurements agreed with expected droplet diameters to within the droplet generation accuracy for droplets above 15 μm diameter, and had a measurement accuracy of about 2 μm for smaller droplets.
