PARTICLE MOVEMENT IN A GAS-SOLID FLUIDIZED BED

[摘要] References(1)The photographs of particle movement were taken in a two-dimensional fluidized bed and statistically analyzed. The circulation of the solid phase was proved to exist from the mean particle velocity and the scale of movement concerning space and time was obtained from the autocorrelation coefficient of particle velocity. These informations will be available for simulating the solid mixing in fluidized beds.
