A fluidized bed is a type of chemical reactor in which a particle bed is contacted by an upward-flowing fluid stream. The resulting fluid-particle suspension takes on fluid-like properties that the particles alone cannot attain. Fluidized beds have been employed industrially for more than 80 years, but significant uncertainty continues to exist regarding the nature of the complex multiphase flow inside the bed. Hence design, scale-up, and troubleshooting of fluidized systems can carry significant technical and financial risk.

流化床是一种化学反应器，其中颗粒床与向上流动的流体流接触。由此产生的流体-颗粒悬浮液呈现出单独颗粒无法获得的流体性质。流化床已在工业上使用了80多年，但关于床内复杂多相流的性质仍然存在很大的不确定性。因此，流化系统的设计、放大和故障排除可能会带来重大的技术和财务风险。
