| Abstract: | In order to investigate the fluidization characteristics in fluidized bed with silicon powder particles, the Computation Fluid Mechanics （CFD） was used to simulate three-dimensional gas-solid flow hydrodynamic characteristics in turbulent fluidized bed under different operation conditions. The Eulerian-Eulerian multiphase model and the SIMPLE algorithm were adopted to analyze the process of bubbles formation, growth and vanishing;and based on the kinetic theory of granular flow, the gas-solid flow characteristics in fluidized bed were studied. The results show that the three-dimensional simulation can provide the performance of the particles in the fluidized bed directly, and provide effective basis for industrial production and application. |
