The properties of solid and fluid alone will determine whether smooth or bubbling fluidization occurs. 仅仅固体和流体的性质就能决定产生的是平稳流化还是鼓泡流化。
It has shown that gas-solid fluidized bed with large-particle is stable in bubbling regime and liable to slugging fluidization, so it had better be operated in shallow fluidized bed and low operating fluidizing number. 研究结果表明:大颗粒气固流化床平稳地运行在鼓泡床阶段,但较易发生节涌现象,适合浅床操作,且操作流化数较低;
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. 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。
Effect of operation temperature on transition from bubbling to Turbulent Fluidization 操作温度对鼓泡流化向湍动流化转变的影响
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. 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。
The turbulent fluidization is a flow regime between bubbling and fast fluidization. 湍动流态化是介于鼓泡流态化和快速流态化之间的一种流型。
In recent years, with the rapid development of traditional industries, the advantages of turbulent fluidization are increasing significantly over bubbling fluidization, and thus its application becomes more widely, arousing the interest of many experts and scholars. 近年来,随着传统工业的快速发展,湍动流态化相对鼓泡流态化有着越来越显著的优势,因而应用越来越广泛,引起了众多专家学者的研究兴趣。
