Abstract

A Phase Doppler Spray Analyzer (P/DSA) and a laser imaging system (LIS) was used to study the response of a P/DSA to non-spherical particles. Methanol particles with an aspect ratio ranging from 0.7 to 1.4 were used in this investigation. Results indicated that the P/DSA was quite sensitive to particle shape. A Berglund-Liu generator was used to produce particles of 98 um (volumetric diameter). The P/DSA instrument measured particle sizes ranging from 142 μm for a particle of aspect ratio 0.7 to 84 μm for an aspect ratio of 1.4. Particle diameters based on averaged x and y diameters for the laser imaging system ranged from 95 μm to 92 μm over the same range of aspect ratios.
