“…As pointed by Achim et al (2002), the factors can be classified as particle characteristics, mechanical design and operating conditions. Some previous experimental studies have focused on bubble and particle behaviors (Kobayashi et al, 2000, Ozawa et al, 2002, tube attrition, erosion or wastage (Bouillard and Lyczkowski, 1991;Lee and Wang, 1995;Fan et al, 1998;Wiman, 1994), heat transfer (Wong andSeville, 2006, Wiman andAlmstedt, 1997) and gas flow regimes (Wang et. al, 2002).…”

“…Since the droplets are moving, the scattered interference pattern sweeps past the receiver aperture at the Doppler difference frequency, which is proportional to the droplet's velocity. The spatial frequency of the fringe pattern is inversely proportional to the droplet's diameter (Lee & Wang 1994, 1995.…”

Particle characterization is an important component in product research and development, manufacturing, and quality control of particulate materials. In this study a laser-based phase Doppler particle analyzer (PDPA) was used to measure particle size and velocity. Two different particles including humid particles and fog particles were tested using the PDPA. Several tests were conducted under different conditions and all data were analyzed using the statistical method and analysis of variance (ANOVA) to see which factor affects particle performance. The humid particle flow rate has a significant effect on both the particle mean diameter and the particle mean velocity with 90% confidence. The type of oil particles has a significant effect on the particle mean velocity with 90% confidence.

“…John et al [13] found that the triboelectric current to a metal surface varies linearly with the momentum of the particles impacting the surface, while Zhu and Soo [14] found that the relationship is no longer linear when dense gassolid suspensions, such as those found in a fluidized bed, are considered. Lee and Wang [15] successfully used triboelectric probes, referred to as "electrostatic probes" in their work, for exploring the solids flow pattern around a vertical tube in a gas-solid fluidized bed. Da Silva et al [16] found that the triboelectric current measurements could be used for relative characterization of erosion rates in a cyclone.…”
