流化床的数值模拟在流化床结构设计和放大中有着重要作用，目前得到广泛应用的多种基于CFD的数学模型在工业尺度的计算中存在不同缺陷。本文引入一种基于CPFD理论的方法，对射流流化床和鼓泡流化床分别进行了数值模拟，结果显示该方法能够有效模拟大量颗粒的两相流体系，反映颗粒和流体的真实运动状态。

The simulation of fluidized bed reactor is important in the structure design and technologyoptimization, the commonmodels based on CFD havedefectsrespectively. In thispaper, a CPFD modelwasused to simulate the jetting fluidized bed and bubbling fluidized bed.The result shows that the model can effectively display the fluidized phenomena in the reactor and the particle\bubble motion.
