Research on the Effect of Distributor Aperture Ratio on Fluidization Quality of Vibrated Fluidized Bed

In this paper, combining with the experimental data in the reference, the purpose is to research effect of three different aperture ratios (α=6%, α=9%, α=12%) of distributor on the fluidization quality of vibrated fluidized bed (VFB). Euler-Euler model in Fluent is used to simulate the flow state. User-defined functions are used to define vibration model, and the distributor is simplified based on the porous media model. The results show that the introduction of the distributor can improve uniformity and quality of the fluidization. The aperture ratio of distributor has little influence on material distribution, however, the uniformity of the fluidization is improved with the decrease of the aperture ratio.
