鼓泡流态化

在鼓泡流态化状态下，气速是流化床气泡行为的主导因素，搅拌桨转速的增加对气泡产生的频率无明显影响但可使气泡的直径变小。

Gas velocity was the major cause for the pressure fluctuation in the bubbling fluidization regime and increasing rotation speed of stirrer blade had little effect on the bubble frequency , but made the bubble size smaller obviously .

当搅拌转速增加到一定程度后，压力脉动的功率谱主频等于搅拌桨转动频率，流化床从鼓泡流态化状态转化为散式流态化状态。

Main frequency of the power spectrum is equal to the rotation frequency of stirrer blade , and the fluidized bed transits from the bubbling fluidization regime to the particulate fluidization regime with the increasing rotation speeds of stirrer blade .
