Dispersion Behavior of Coarse Particles by Lateral Vibration under Microgravity [Translated]†
We studied coarse particle behavior in a laterally vibrated vessel under microgravity. Vibration conditions were a frequency of 75-150 Hz and a displacement amplitude of 86-310 μm. The two dimensional displacement distribution of particles moving in three dimensions was measured by particle image sampling within the depth of field. Observations revealed a saddle-shaped distribution in which concentration was higher at the center in the lateral direction and the ends in the longitudinal direction. This tendency became distinct with increasing total particle concentration. The round corners of the vessel made the distribution more uniform due to enhanced circulation. We also found that particle concentration increased with velocity amplitude.† This report was originally printed in J. Soc. Powder Technology, Japan. 34(11), 834-839 (1997) in Japanese, before being translated into English by KONA Editorial Committee with the permission of the editorial committee of the Soc. Powder Technology, Japan.
