Research output: Contribution to journalArticlepeer-review


The characteristics of particle fluctuation was researched through statistical analysis of time series of solid concentration, solid velocity and solid momentum by using FFT technology. The results are as follows: the gas-solid is mixed better in circulating fluidized bed. High frequency gas-solid mixing occurs when solid particle concentration is between 0.04-0.4. Too high concentration of particle will deteriorate fluctuation in circulating fluidized bed.
