This paper presents the research work on the mechanism of flow regime transition (from bubbling to turbulent fluidization) in gas-solid fluidized beds. Combined with statistical measurement in time domain
coherence function was employed to analyze the pressure fluctuation in the bed. When the breaking of bubbles dominates over coalescence
turbulent fluidization occurs. This mechanism was directly proved by the experimental results.
