Abstract:
Three distances (1.2, 3.0 and 7.6 m) and 4 methods (complete diagonal swing, impinger, top diagonal swing and vertical swing) were compared in analyzing the droplet spectra of electrically generated ULV aerosol clouds. There were no significant differences among the 4 methods and no interaction between method and distance. However, when compared over distance, the percent variability indicated the complete diagonal swing provided the most consistent results. Two additional methods (pendulum and settling chamber) were compared with the original 4 methods at 1.2 m only. At this distance, there was no significant difference among the 6 methods.
